Applications are invited for a research studentship in the field of Female ACL injury in Elite Football leading to the award of a PhD degree.  The post is supported by a bursary and fees (at the UK student rate) provided by the Football Association.

The project will be managed jointly by The Football Association (FA) and Imperial College (IC) with expert surgical input from Fortius Clinic, London. The work will largely be ‘in the field’ with a base at the Biomechanics research group at IC’s South Kensington campus.

It is expected that the project will entail development and use of in-depth evaluation methods that can be used with identified players and the participating clubs to understand current training methods, development pathways and physical development programmes and their relation to ACL injury, to document histories of those who have been injured and to evaluate post-injury treatment/rehabilitation methods and the long-term outcomes in terms of return to play at elite level. This work will lead to evidence-based recommendations for injury prevention and return to sport for the women’s professional game in England. It is expected that this project will identify key modifiable risk factors, leading to improvements in training/rehabilitation methods which can be widely implemented to help improve outcomes for players throughout the women’s game.

Applications are invited for a research studentship in the field of Additives for EV lubrications leading to the award of a PhD degree.  The post is supported by a bursary and fees (at the UK student rate) provided by Shell UTC. To be eligible for support, applicants must be “UK Residents” as defined by EPSRC. 

This project is a part of a large effort for our zero transition initiatives. Our goal is to design the best coolant and lubricant for EV through a fundamental understanding on how we may control the behaviour of additives under the influence of an electric field. This has a direct impact on the performance and reliability of EV. Ultimately, we aim to revolutionise lubricant technology by creating smart, responsive lubricants that can lubricate on demand!

In this experimental project, the PhD researcher will examine how an application of an electric field affects the behaviour of various additives. This will involve both fundamental and applied studies. The researcher will design experimental setup that allows various additives properties to be measured in situ and in real time during rubbing. This will allow a direct correlation between additive behaviour and tribological performance of a lubricant. The project will also be supplemented using other techniques, include advanced laser spectroscopies, and various surface and chemical characterisation techniques.

This project will be based at Imperial College with regular interaction with our project partners. The PhD researcher will be a part of the Shell UTC and the Tribology Group. It offers a vibrant, multidisciplinary and multicultural working environment. Laboratories were recently refurbished and are well equipped with an extensive range of instrumentation and extensive computer facilities.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will hold, or be expected to achieve, a Master’s degree or a 4-year undergraduate degree at 2:1 level (or above) in a relevant subject, e.g. Chemical or Mechanical Engineering, Materials, Chemistry, Physics or a related field. You will have an enquiring, rigorous and hands-on approach to research, together with a strong intellect and disciplined work habits. An interest in experimental work and development is essential, as are good team-working, observational and communication skills.

Applications are invited for a research studentship in the field of energy storage, leading to the award of a Ph.D. degree. The focus will be on advancing fundamental understanding of thermal and fire hazards of lithium-ion batteries, which will underpin the development of safety control strategies and countermeasures for lithium-ion batteries. The post is supported by full bursary and fees at the UK student rate for ‘home’ students.

https://www.imperial.ac.uk/study/pg/apply/fees/fee-status/

Project Description

Lithium-ion batteries play an important role in advancing the electrification of road transport and facilitating a swift transition towards renewable energy sources. Although they are generally stable under normal conditions, lithium-ion batteries are inherently flammable and susceptible to thermal runaway when exposed to abuse or internal defects. As the demand for lithium-ion batteries continues to soar, understanding their thermal and fire hazards throughout their lifecycle has become imperative.

This research aims to contribute fundamental insights into the intricate interplay between battery cycling conditions and thermal and fire hazards. The research will involve the coupling of a cutting-edge battery electrochemical model with an advanced thermal runaway model, which will be parameterised and validated using experimental data. The project outcomes will lay a scientific foundation for enhancing safety of future energy storage systems.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will hold, or be expected to achieve, a Master’s degree or a 4-year undergraduate degree at 2:1 level (or above) in a relevant subject, e.g. Chemical or Mechanical Engineering, Materials, Chemistry, Physics or a related field. You are expected to have an enquiring and rigorous approach to research, complemented by a strong intellect and disciplined work habits. A willingness to work on both computations and experiments, with excellent teamwork and communication skills, is essential.

Applications are invited for a research studentship in the field of future aeroengine technology, leading to the award of a PhD degree.  The post is supported by a bursary and fees (at the UK student rate) provided by the EPSRC, with a generous bursary top-up from industrial funds.  EPSRC candidates should fulfil the eligibility criteria for the award. 

The design of efficient and safe next generation gas turbines requires among other things a reliable control of rotor vibrations to prevent a rapid loss of structural integrity during operation. Future engine designs require novel vibration management concepts that can replace conventional rotor damping solutions, such as squeeze film dampers (SFDs). This PhD research aims to deliver such a novel vibration management mechanism that shall be scalable, weight efficient and capable of operating across a wide frequency and load ranges (from normal vibration to extreme fan-blade-off loads) in a safety critical aerospace environment. The aim thereby is to research different potential energy absorption approaches (eg. the use of structural non-linearity, smart materials, topology optimisation, …), evaluate their potential with respect to shaft damping in turbo machinery, provide the physical understanding and numerical tools to analyse, predict, select, optimise and design a novel shaft damping solution, and demonstrate the designs feasibility with a simple proof of concept setup on a laboratory rig. The student will be a member of a Vibration UTC, funded by Rolls-Royce 35 years ago with a long demonstrable history of delivering state of the art research and producing world-class specialists both for industry and academia. The candidate will have the opportunity to an internship at Rolls-Royce during their PhD.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 1st class honours degree in mechanical engineering or a related subject, and an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits. An interest in numerical and experimental dynamic techniques is essential.  Good team-working, observational and communication skills are essential.

Applications are invited for a research studentship in the field of Mechanics of Materials leading to the award of a PhD degree.

The aim of this research is to develop FEA simulations that can answer the question of how long a running shoe will last. The developed simulations will enable cost efficient virtual tests to be performed. The focus is on foam materials with varying relative densities. To develop design tools for longer lasting shoes with increased fatigue (product) life, you will be performing simulations at two length scales: a) Microscale: a micromechanical model of the foam architecture to obtain homogenised bulk properties, and b) Macroscale: a simulation of the shoe during running (one cycle and multi-cycles). The microscale model will be informed through imaging studies of the foams through x-ray micro tomography using computerised tomography (CT). The reconstructed 3D geometries will be meshed to perform finite element (FE) simulations to derive predictions of the mechanical properties of the foam. The simulations will be validated through macroscopic coupon test experiments. You will then perform virtual tests of the shoe at the macroscale. The boundary conditions in this case will need to be obtained from literature on the biomechanics of running. In both scale simulations, emphasis will be given on determining and calibrating the right constitutive models such that progressive damage of the material is enabled. Challenges will need to be met regarding alleviating mesh sensitivity of results inherent in damage models and simulating fatigue loading within reasonable computational running times.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 1st or 2:1 class honours degree in mechanical engineering, physics, mathematics, or a related subject, and an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits. An interest in Mechanics of Materials is essential.

Applications are invited for a research studentship in the development of novel lubricating fluids for application in drivetrains of passenger electric vehicles (EVs), leading to the award of a PhD degree. This is a fully funded iCASE PhD studentship in collaboration with a major premium passenger vehicle manufacturer. The studentship covers a tax-free bursary of around £27,000 per annum, full tuition fees, and all project costs. The studentship is available to suitably qualified UK and overseas candidates.  

Effective lubrication of electric vehicle drive units presents unique challenges in terms of lubricant formulation. An EV drive unit lubricating fluid is required to provide adequate protection to gear and bearing surfaces under high torque – low speed operating conditions, while minimising churning losses at high speeds and low torques. The former requires a high viscosity fluid and the latter a low viscosity one. Furthermore, in most modern EVs the same fluid is used to lubricate the gearbox and to cool the e-motor, which imposes additional requirements on the EV fluid of having a high specific heat capacity and suitable copper compatibility. Although traditional hydro-carbon based oils may excel in some of these aspects, such as offering superior surface protection, they may no longer offer the optimum combination of properties to adequately satisfy this whole set of requirements.

This project aims to help develop new EV drivetrain fluids to address these competing requirements. In particular, we will explore how best to balance fluid’s cooling capability with its lubricating performance. To achieve this, the work will explore tribological performance of several unconventional lubricants, including for example, water-based ones. The key benefits of a water-based lubricant in EV drive train applications are its superior cooling performance, which can offer potential benefits in e-motor efficiency, and lower transmission losses at higher vehicle speeds. However, water-based fluids are generally poor lubricants compared to conventional oils; this is due to their inferior hydrodynamic film forming abilities, caused by low viscosity and low pressure-viscosity coefficient, as well as inferior tribofilm formation under low speeds. The project will explore the tribological behaviour of these and other candidate fluids, with the aim of producing practical guidance on potential fluid formulations for optimum efficiency and reliability of electric drive units in passenger EVs. 

The successful candidate will have regular opportunities to present their work at major international conferences in Europe, USA and Japan, and will be expected to publish the results of this research through a series of journal papers. They will also closely communicate with the industrial partners on this project, including visiting their research facilities.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a good degree in Mechanical Engineering, Chemical Engineering, Physics or a related subject, with at least a 2:1 equivalent degree classification. Your past studies and experiences will demonstrate a rigorous approach to research, disciplined work habits and an enquiring mind. Good written and oral communication skills are essential.

Applications are invited for a research studentship in the effects of hydrogen on the performance of machine elements, leading to the award of a PhD degree. The studentship is fully funded through a research agreement with our industrial partners, a large multinational company, and covers a tax-free bursary of around £27,000 per annum, full tuition fees, and all project costs. The studentship is available to suitably qualified UK and overseas candidates.  

Hydrogen is playing an important role in the global efforts for clean energy transition. Its most obvious uses are in fuel cells and hydrogen combustion engines, but hydrogen is also increasingly used in industry, for example, in green steel production. However, storage, transport and use of hydrogen present unique challenges in ensuring reliability of machine components which may be exposed to hydrogen at some point in their life cycle. One known issue is the phenomenon of hydrogen embrittlement of steels, where permeation of hydrogen into the steel matrix adversely affects steel mechanical properties and hence increases the risk of failure. Machine elements, such as bearings and gears, are important examples of engineering components that are believed to be susceptible to hydrogen embrittlement. It has been postulated that hydrogen can diffuse into the rubbing steel surfaces of these components and consequently, accelerate the initiation and/or propagation of contact fatigue cracks. One example where this phenomenon has been suggested to be of significance are wind turbine drive trains, many of which experience mechanical failures much earlier than predicted by conventional theories. To help address some of the relevant questions, this project will make use of world-unique analytical and test equipment to systemically investigate the potential influence of hydrogen on damage and failure in lubricated rolling-sliding contacts of hard steels, representative of those found in machine elements such as bearings and gears. The results of this project are of practical significance in the design and operation of wind turbines, fuel cells, and many other mechanical systems across automotive, industrial and energy sectors.  

The project will utilise existing test equipment available in the Tribology Group at Imperial, including the triple-disc contact fatigue rig and ball-on-disc tribometers, to systematically evaluate the initiation and progression of surface damage in lubricated rolling-sliding contacts under conditions that may promote uptake of hydrogen by the rubbing steel surfaces. A selection of lubricants and steels will be included in the study. Crucially, the tested specimens will then be analysed using a world-unique analytical set-up, referred to as ‘cryo atom probe’, available at Imperial that is designed to detect and locate atomic hydrogen within the steel matrix. Historically, the primary issue with studying hydrogen embrittlement of steels has been the inability to observe mobile hydrogen atoms within the steel specimens. The standard techniques, such as TDA, that are commonly used to assess the amount of hydrogen in a test specimen, are only able to provide a measure of the total hydrogen content in the sample, but do not provide the key information on the location of the hydrogen atoms within the matrix and do not distinguish between the trapped, and hence largely inconsequential, hydrogen, and the potentially damaging mobile hydrogen. The cryo-atom probe overcomes this, and other, limitations by keeping the test sample under cryo conditions from the moment it is removed from the test chamber through every stage of analysis, including FIB, SEM, TEM and atom probe itself as needed. This facility has only recently become available through a multi-million-pound investment supported by public and industrial funding. This set of experiments will enable us to (i) conclusively confirm whether hydrogen permeates into the rubbing steel surfaces under any given contact conditions and lubricants, (ii) establish any preferred locations where the hydrogen migrates within the steel matrix, for example, the vicinity of a fatigue crack tip, and (iii) link these observations to the mechanisms of any surface damage observed in the initial tests. Given the unique set of cutting-edge testing and analytical equipment available to this project, it is hoped that this research will provide ground-breaking insights on the effects of hydrogen on the performance of tribological contacts with far reaching impact across multiple applications.   

The successful candidate will have regular opportunities to present their work at major international conferences in Europe, USA and Japan, and will be expected to publish the results of this research through a series of journal papers. They will also closely communicate with the industrial partners on this project, including visiting their research centre in Europe.

Applications are invited for a PhD research studentship in the field of high-fidelity modelling of clad ballooning in nuclear reactor loss-of-coolant accidents.  The post is supported by a bursary and fees (at the UK/EU student rate) provided by the EPSRC and the National Nuclear Laboratory (NNL). Candidates should fulfil the eligibility criteria for the award. Please check your suitability.

The loss-of-coolant accident (LOCA) is generally the limiting design-basis accident in a LWR. In the event of such an accident, the fission chain reaction is automatically shutdown, however there remains ‘decay heat’ generation, perhaps 7% of operating power, for some hours following the accident. Removal of this decay heat requires that sufficient coolant can be brought into the core, and that the core, during this time, retains a "coolable geometry". This is not guaranteed - excessively hot, internally pressurised fuel pins can deform - so called ‘clad ballooning’ - and possibly form blockages to the flow. 

A major focus of the reactor safety case is therefore to ensure that the consequences of a LOCA are manageable. To do so, we must understand and model both the complex mechanical behaviour of the fuel and outer cladding, and the coolant flow over the fuel pins. Indeed, these effects are strongly interdependent.

The aim is to develop a state-of-the-art computer code system to predict the 3-D clad ballooning behaviour of rods in a light water reactor (LWR) fuel bundle during a loss-of-coolant accident (LOCA). The code system will involve the dynamic coupling of a state-of-the-art 3-D fuel rod performance code with a state-of-the-art 3-D thermal-hydraulics code, will be validated using experimental data, and will be demonstrated for an LWR fuel assembly. 

The position is a collaboration between the Nuclear Engineering Group within the Mechanical Engineering Department and the Engineering Alloys Group within the Department of Materials. This PhD is funded by the UKRI/EPSRC and the UK National Nuclear Laboratory (NNL).

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 1st class or 2:1 honours degree in mechanical engineering or a related subject, and an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits. An interest in fracture mechanics is essential.  Good team-working, observational and communication skills are essential.

Applications are invited for a research studentship in the field of fracture and high strain-rate materials characterisation, leading to the award of a PhD degree.  The post is supported by a bursary and fees (at the UK/EU student rate) provided by AWE plc.

This PhD project aims to advance our understanding of the influence of strain rate and sample size on the fracture toughness of nuclear grade A508 forged steel and 3D printed Ti-6Al-4V manufactured through laser powder bed fusion. Strain rate is known to affect the mechanical properties of alloys, especially the yield strength and fracture toughness. Conventional fracture toughness methods used under quasi-static loading, such as pausing and unloading tests at predefined displacements do not work at high-speed. This leads to uncertainty in predicting the structural integrity of structures which may experience high speed loading scenarios in service. In this PhD you will develop innovative high-speed experimental methods to overcome the limitations of the established quasi-static approach. This will include the design and development of a method to load a compact tension (CT), or single edge notch bend (SENB) specimen, at high-speed (>10 m/s) to a fixed displacement to prevent the specimen fully fracturing into 2 pieces. You will learn to use high-speed photography and apply techniques to measure sample deformation.

Applications are invited for a research studentship in the field of high strain-rate materials characterisation, leading to the award of a PhD degree. The post is supported by a bursary and fees (at the UK/EU student rate) provided by AWE plc.

This PhD project aims to develop innovative experimental methods to measure the stress-strain response of soft materials at high strain-rates.  Although the testing of metallic samples under these conditions is fairly mature, measuring the properties of softer materials (such as organic materials and polymer bonded explosives) is much more challenging. Dynamic loading of soft materials is challenging due mismatch in stiffness between the samples and loading fixture. Even holding the sample in place can be difficult due to their low stiffness and tendency to deform under their own weight. These difficulties can give rise to large uncertainties in measurements of mechanical properties in soft materials, especially in non-compressive loading. In this PhD you will advance the state-of-the-art to overcome these limitations through the development of novel dynamic testing equipment at strain-rates of 1,000/s (faster than a car crash) and above. The approach taken will be a miniaturised Split Hopkinson Pressure Bar (SHPB) design that will enable testing of soft materials that are difficult to prepare into test specimens and introducing a high level of automation into the test procedure to reduce or eliminate operator variability. You will learn to use high-speed photography (think The Slow Mo Guys) to measure sample deformation and investigate the effects connection arrangement between the loading bars and sample. You will also have the opportunity to develop finite element models to further our understanding of testing these materials at high-strain rates and to travel and present your work at international conferences.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 1st class or 2.1 honours degree in mechanical engineering or a related subject, and an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits.

Applications are invited for a research studentship in the field of in-process evaluation of battery electrodes, starting from Oct 2024 onwards and leading to the award of a PhD degree. The post is supported by a bursary and fees provided by the Department of Mechanical Engineering. UK students are prioritised but overseas students will be considered too.

The research involves development and validation of novel NDE methodologies for characterising the physical properties of battery electrodes, during and after the manufacturing processes of drying and calendaring. Aimed at reducing the currently very-high scrap rates in gigafactories around the world – thus could lead to significant economic values - the research will develop a comprehensive framework to describe, simulate, and experimentally acquire and interpret guided ultrasound propagating along the porous-solid-porous electrode structures. This will enable in-depth investigations on the structural properties of the electrodes, e.g. the polymer setting mechanisms during drying, which will be combined with destructive adhesion testing for validation, e.g. on the flexible-arm peel test developed within the department. Strategies for improvement and closed feedback loop will then be assessed and employed, based on the deficiencies found. We will also study the accelerated degradation in use, caused by adhesion issues of the multilayer electrodes, and tune the NDE techniques to detecting such defects at the manufacturing stage. It will be a collaboration between the NDE and Adhesion/Adhesive groups, which are both world leaders in their respective research areas.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 1st class honours degree in mechanical engineering or a related subject, and an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits. An interest and good skills in experimental work are essential, so are good team-working, observational and communication skills.

Applications are invited for a research studentship in the field of laser processing of materials (graphene-enabled laser joining and repairs) leading to the award of a PhD degree.  The post is supported by a bursary and fees (at the UK student rate) provided by the PhD Scholarship of the Department of Mechanical Engineering.

In the era of industrial sustainability, there's a growing emphasis on prioritizing material repair and reuse over incessant production. The principles of "repair, don't replace" and "First Time Right" are at the forefront, highlighting the need for enhanced quality control and sustainable fabrication methods. As the complexity and scale of the components we produce continue to expand, the demand for reliable methods to securely join dissimilar materials has surged. Laser processing, especially laser welding, emerges as a promising solution, particularly in industries like aerospace and transportation.

However, a significant challenge arises when it comes to materials that do not readily absorb laser light, rendering them unsuitable for laser processing. This is particularly relevant for refractory materials, which require exceptionally high temperatures for melting or sintering. The effective conversion of laser light into heat is crucial in these cases.

Our research project aims to address this challenge by exploring a universal enhancer – chemically modified graphene. Graphene possesses the unique ability to efficiently absorb laser light across a broad range of wavelengths and convert it into heat through the photothermal effect. When graphene is introduced to refractory compounds, it enhances their laser processability, making them suitable for laser melting and sintering manufacturing methods. Our research will involve the synthesis of various graphene variants, blending them with feedstock powders, and using them to create joints and repairs. Throughout the project, we will conduct continuous characterization to understand how the composition of the materials and the presence of graphene affect laser processability and the quality of the joints.

In addition to this, we will develop a novel in-situ non-destructive evaluation method as part of the project. This method will enable us to monitor the quality of joints by utilizing high-frequency modulations of the laser source, which emit ultrasonic waves that can be detected and used for inspection.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London, holding or expecting a First-Class or high 2:1 MSc degree in engineering, materials, chemistry, physics or related fields. Keen to investigate graphene's impact on laser processing, they'll work on experiments and tech development, which will require teamwork, observation, and communication skills. For eligibility, applicants must be "UK Residents" per EPSRC's definition (https://www.ukri.org/what-we-do/developing-people-and-skills/esrc/funding-for-postgraduate-training-and-development/eligibility-for-studentship-funding/).

Applications are invited for a research studentship in the field of Battery Electrochemistry, leading to the award of a PhD degree.  The post is supported by a bursary and fees (at the UK student rate) provided by industrial funding. 

This PhD project will focus on lithium iron phosphate (LFP) batteries, with the aim to gain fundamental understanding on how they degrade under both battery energy stationary storage (BESS) and Electric Vehicle (EV) use cases. The increase in use of LFP is due to their lower raw material cost vs Nickel Manganese Cobalt cathodes (NMC) lithium-ion batteries, as well as LFP’s improved aging and safety profile vs NMC. However, LFP does have lower energy density and brings a unique set of challenges vs NMC, specifically around state of health and charge determination, as well as degradation mechanisms. The research will develop physics-based and distributed models able to reproduce the limiting degradation mechanisms of LFP cells and will be supported by extensive tests that will be designed and conducted to target such mechanisms. The PhD candidate will work closely with our industrial partner and to the research group members to answer the research questions, which are centered around creating knowledge to determine the thermal management requirements for optimal performance and aging of LFP batteries.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 1st class honours degree in mechanical engineering or a related subject, and an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits. An interest in batteries and vehicle electrification is essential.  Good team-working, observational and communication skills are essential.

The useful life of liquid lubricants and greases is limited by the fact that they oxidise in air. This requires regular oil change and disposal, limits the temperatures at which lubricants can be used, and greatly constrains the application of environmentally-friendly vegetable oils. Prevention of lubricant oxidation would thus make a major contribution to sustainability and the environment. Our group is developing an exciting concept to prevent lubricant oxidation via “inerting” closed lubricated systems. This concept can potentially bring significant benefit to performance of transmissions of electric vehicle, wind-turbine, industrial gearboxes and hydraulics. For more details, please see the link below:

Zhang, J., Wong, J.S.S., and Spikes, H.A., 'Lubrication in an Inert Atmosphere - a New Era in Lubricant Technology', STLE Annual Meeting, Long Beach, May 24th 2023.

Applications are invited for a research studentship in the field of lubrication and tribochemistry, leading to the award of a PhD degree. The post is supported by a bursary and fees (at the UK student rate) provided by Shell. The studentship is for 3.5 years, starting as soon as possible and will provide full coverage of standard tuition fees and an annual tax-free stipend of approximately £20k. Home (based on UKRI criteria) and international candidates will be considered.

This experimental project will study performance of lubricants in inert conditions. Using advance tribological and analytical techniques, you will answer the following research questions: (i) Do lubricants designed to work in air function effectively in the absence of oxygen and if now, why not and how can they be changed? (ii) How, if at all. do lubricants degrade in the absence of oxygen? The answers to these will then be used to formulate and apply inerted lubricants in real applications.

The project will be hosted by The Tribology Group at Imperial College, which is a vibrant, world-leading research group with unparalleled experimental and modelling equipment facilities. You will be supervised by Dr Janet Wong and Professor Hugh Spikes. You will be expected to study at a Shell location for a minimum period of 3 months and be part of a larger community of Shell-funded researchers in the Group who are working on lubricant and electric vehicle-related projects.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 1st class honours degree or a high 2:1 degree at Master level (or equivalent) in Chemical Engineering, Materials, Chemistry or a related science and branch of engineering. You have an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits.  Good team-working, observational and communication skills are essential.

Applications are invited for a research studentship in the field of Molecular Simulations of Food Biotribology, leading to the award of a PhD degree.   The post is supported by a bursary and fees (at the UK student rate) provided by the Mechanical Engineering Department, and it is open to ‘home’ students: https://www.imperial.ac.uk/study/pg/apply/fees/fee-status/. The project will be supervised by Dr James P. Ewen, Dr Marc Masen, Prof. Philippa Cann (Tribology Group), and Prof. Maria Charalambides (Soft Solids Group).

The project will involve applying molecular dynamics simulations to study food biotribology inside the mouth. This is important because friction and lubrication play a crucial role in determining the sensory attributes and perceived quality of food products. Coarse-grained molecular models of biological surfaces in the mouth (e.g., tongue, palate, and teeth), saliva (water, electrolytes, and mucus), and specific food components (e.g., proteins, lipids, and carbohydrates) will be developed. These models will then be used in non-equilibrium molecular dynamics (NEMD) simulations to study the rheology and friction of food components under physiological conditions representative of chewing and swallowing. We will incorporate information from the molecular simulations into larger-scale models, such as the finite element method (FEM). The developed models will be validated against experiments to measure the wettability and friction of food formulations using biomimetic surfaces.

The proposed project will contribute to the fundamental understanding of food biotribology, addressing key challenges in food science and technology. By elucidating the molecular basis of sensory perception and mouthfeel, the findings will facilitate the design of healthier, more appealing food products with enhanced nutritional value and consumer acceptance. Furthermore, the insights gained from this project can be extended to other applications, such as oral medicines and protein shakes, where biotribological interactions inside the mouth also play a crucial role in product performance and consumer satisfaction.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a first or upper second-class honours degree in mechanical engineering, bioengineering, chemistry, physics, materials science, or a related subject, and an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits. Good team-working, observational and communication skills are essential. An interest in advanced multi-scale modelling is desirable.

Improved spatial localisation of ultrasonic scan data on physical assets

The drive towards Industry4.0 and IoT enabled technology is leading to increased demand for digitalisation of NDE data and reporting. As operators become less involved in the process of data acquisition and on the spot analysis, the localisation and registration of measurement data is becoming increasingly important. In unstructured environments, standard robotic localisation techniques today have uncertainties in the order of 0.01m. This might be sufficient for single shot inspection assessments but is not good enough for trend estimation over time because subtraction of two spatially mismatched defects will result in large errors in the estimated change of defect size over time and hence trending errors.

This project aims to address this problem by researching different external and internal localisation referencing techniques to register data and efficient techniques to handle their temporal evolution. We will consider SLAM (simultaneous localisation and mapping) based on cameras for external features and inspection data (ultrasound will be used in the project) for the acquisition of internal data. The project will build on the results of the feasibility study on the “stitching  of ultrasonic phased array scan data” that was completed in 2021.

To be eligible for support, applicants must be “UK Residents” as defined by the EPSRC. Please check your suitability at the following here. The studentship is for 3.5 years starting in 2023 and will provide full coverage of standard tuition fees and an annual tax-free stipend. Funding is through the Industrial Cooperative Award in Science & Technology (iCASE) scheme funded by the EPSRC and NDEvR Ltd (the legal entity representing the >10 industrial and ~8 university members of the UK Research Centre for NDE- RCNDE consortium). The students will be hosted at one of the industrial partner company locations for a minimum period of at least 3 months over 4 years and offered industrial mentorship during the project. The student will be part of a larger community of industry funded researchers in NDE at Imperial and the partner institutions.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. Applicants should hold or expect to obtain a First-Class Honours or a high 2:1 degree at Master’s level (or equivalent) in Mechanical Engineering, another branch of engineering, Materials, Physics, Chemistry or a related science. We expect you to have an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits. An interest in developing experimental and/or modelling methods to investigate the effect of electric fields on engineering interfaces across the scales is essential. Good team-working, observational and communication skills are essential.

Applications are invited for a research studentship in the field of clean, safe and competitive future aero engine development, leading to the award of a PhD degree.  The post is supported by a bursary and fees (at the UK student rate) provided by the EPSRC, with a generous bursary top-up from industrial funds. EPSRC candidates should fulfil the eligibility criteria for the award. 

The research will be conducted within the Vibration University Technology Centre (VUTC), sponsored by Rolls-Royce Plc to facilitate vibration related research. It involves the development and validation of novel nonlinear structural dynamic approaches to predict damping of aero engines components. Non-linear dampers are essential for aero-engine component safety, reliability and performance. Improved, validated non-linear contact prediction will allow the design of more robust, lighter weight components, improving Specific Fuel Consumption, Time on Wing and operational safety. As step changes in technologies and engine usage are made to meet Net Zero targets, the improved non-linear dynamic prediction capability will greatly  enhance modelling techniques de-risking technology developments.

Recent research in the VUTC has shown that the performance of frictional damping, and particularly Under Platform damping in bladed discs in aeroengines, is highly sensitive to the initial loading conditions, potentially limiting, or even negating the advantages of optimised damper designs. This research work will focus on the development of efficient techniques to improve non-linear contact modelling, to include the uncertainties into Under Platform Damper predictions, use these techniques to propose an optimised, more robust damper designs, and validate the new modelling methodology with the help of an existing rotating test bed. The work will be both numerical and experimental, and hence we are looking for a candidate with interest in both areas. The research will be conducted in close collaboration with Rolls-Royce Plc. and offers the opportunity to spend some time in the company for knowledge transfer.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 1st class honours degree in mechanical engineering or a related subject, and an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits.

Applications are invited for a research studentship in the field of vibration and friction, leading to the award of a PhD degree. The post is supported by a bursary and fees (at the UK student rate of approximately £21,000 net per annum) provided by the Department of Mechanical Engineering under the EPSRC Doctoral Training Partnership scheme, and it is open to home students only. 

The research will be conducted in the Tribology Group, one of the largest and most renowned tribology research groups in the world today, collaborating with the government, companies in Europe, USA and Far East, and many universities across the globe. Amongst others, the group focuses on the aviation sector, facing the urgent need to design lighter and more environmentally sustainable aero-engines to target Net Zero goals. Aero-engine manufacturers face the complex challenge of ensuring safety while reducing emissions, a task made daunting by the intricate vibrational behaviour of engine components. Predicting the engine dynamic behaviour is particularly complicated due to the millions of components in contact, whose understanding is limited by a lack of experimental friction data.

This PhD project aims to develop a new experimental technique, and related theory, to monitor friction contacts during vibration. The technique will be based on the use of metamaterials, emerging artificially-engineered structures with the exceptional capability to manipulate how waves propagate. This capability is leading a multi-billion-dollar technological revolution in several applications, including non-destructive evaluation, which will be exploited here to monitor friction. Friction monitoring based on metamaterials has never been proposed before and is an opportunity for a breakthrough in the fields of tribology and dynamics. By joining this project, you can make a tangible impact on the future of aviation, contributing to safer, cleaner, and more efficient air travel.

The work is supported by Rolls-Royce plc, whose senior specialists will provide guidance throughout the PhD. Through the company’s extensive global network, the student will establish contacts with industrial colleagues and leading academic groups particularly in the UK, Germany, and the US. The Imperial academic supervisors include Dr Fantetti (Tribology Group), Dr Hooper (Mechanics of Materials Group) and Dr Renson (Dynamics Group).

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You should hold or expect to obtain a 1st class honours or a high 2:1 degree at Master’s level (or equivalent) in Mechanical Engineering, another branch of relevant engineering, Material, Physics, Chemistry or related science, and willing to start in October 2024 or shortly after.

This PhD is an exciting opportunity for those interested in experiments as well as simulations, ranging topics such structural dynamics, ultrasound and tribology.

Applications are invited for a research studentship in the field of tribology, leading to the award of a PhD degree.  The post is supported by a bursary and fees (at the UK student rate) provided by the Department of Mechanical Engineering, Imperial College London. 

Interfaces between moving surface, covering a vast range of practical applications in industrial and biomedical sectors, are critical in determining efficiency and durability. The research involves design and validation of a novel smart interface. A magnetic field is actively controlled to actuate the rheological / tribological behaviour of magnetorheological fluid between a sliding contact, a non-destructive ultrasonic reflection technique is employed to probe the fluid film thickness, the variation of which is taken into the feedback of the overall closed control loop. This smart interface has a potential in reducing friction and thus energy usage in mechanical transmissions, or enabling intelligent mechatronic systems (e.g., soft robots), where controllable interface friction and fluid film thickness are desired. Also, structural health monitoring can be additional benefit. This project will be mainly experiment oriented, and numerical / analytical modelling will be also promoted.

The PhD will be based in the Non-Destructive Evaluation (NDE) Group and the Tribology Group in the Department of Mechanical Engineering, Imperial College London.  Both are leading research groups in the world, with extensive experimental and numerical research facilities and an international reputation for research excellence. It will be performed in collaboration with other research groups at Imperial College London and other universities.

This project is part of a multidisciplinary project InFUSE whose goal is to study key material and fluid interfaces across a range of application areas with direct impact on the energy transition. Our aim is to create a step-change in the correlative characterisation of interfaces embedded in these systems under realistic environments.

Temperature (and the extraction of heat) plays a very important role in the performance of machines. For example, increased temperature may reduce the viscosity of lubricants, which impacts on friction or wear of machines. It may also lead to increased rate of undesirable reactions, such as corrosion and surface degradation. Overheating also reduces components lives. In the context of EV, increased temperature reduces battery efficiency and poses safety risk. All these applications point to the importance of characterising interfacial thermal conductance at a solid-liquid interface, which is extremely challenging.

In this experimental project, the PhD researcher will characterise the thermoconductance of solid-liquid interfaces in engineering fluids, including lubricants, coolants, and refrigerants. Specifically, the effects of additives, coatings and surface modifications will be investigated. To do so, the researcher will design a setup based on thermoreflectance measurements. Complementary techniques such as QCM, AFM, IR will also be employed. The potential of using thermoreflectance for acquiring film formation kinetics will also be explored.

This project will be based at Imperial College with significant interaction with the project partners, Thin Film Technology Laboratory, Diamond Light Source and Shell. The PhD researcher also will be a part of the Tribology Group. It offers a vibrant, multidisciplinary and multicultural working environment. Laboratories were recently refurbished and are well equipped with an extensive range of instrumentation and extensive computer facilities.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will hold, or be expected to achieve, a Master’s degree or a 4 year undergraduate degree at 2:1 level (or above) in a relevant subject, e.g. Chemical or Mechanical Engineering, Materials, Chemistry, Physics or a related field. You will have an enquiring, rigorous and hands-on approach to research, together with a strong intellect and disciplined work habits.

Applications are invited for a research studentship in the field of Thermofluids and Nuclear leading to the award of a PhD degree. The post is supported by a bursary and fees (at the UK student rate), provided by UKAEA and the Department of Mechanical Engineering. The Department’s entry requirements must be fulfilled for enrolment to this program.

You can check your eligibility and register interest by following this link https://imperial.eu.qualtrics.com/jfe/form/SV_6KiVRAhitEJ30Tc

The focus of the project is the reliable linking of a well characterised experiment with simulation models including the development of the required simulation techniques to be applied in a broad range of fields. A candidate experiment that is going to be used for this purpose is a T-junction experiment, where flows of dissimilar thermal characteristics are mixed. Understanding the thermal behaviour, mixing and flow of dissimilar temperature fluids at a T-junction, is highly relevant for nuclear fusion applications, while also applicable to a wide range of non-fusion relevant cooling systems for high power density thermal applications. The research has mainly been based on numerical simulations, due to the difficulties with experimentation. Therefore, physical understanding of the process is missing and correlations for the effect of turbulence on thermal performance and the design consequences on container geometry are not very well understood. This is important for the improvement and evaluation of numerical models for such flows. The proposed study will deliver new understanding and scaling of T-junction flows by combining experimental and numerical efforts. It is expected that the proposed study will provide guidance for optimisation of plasma-facing component designs and control of cooling systems in near-term applications such as UKAEA Chimera but also future designs for e.g. STEP. The project falls under the topics of Thermal hydraulics and flow mixing of dissimilar temperature flows in T-junction geometries. The student would be based full time at Imperial College London with visits when needed to UKAEA sites and other collaborators.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 2.1 ot a 1st class honours degree in mechanical engineering or a related subject, and an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits.

Applications are invited for a research studentship in the field of “Fundamental understanding of water-based lubricants for hydraulic and EV applications”, leading to the award of a PhD degree. The studentship will be based in the Shell-Imperial University Technology Centre (UTC) for Mobility and Lubricants, which is hosted by the Tribology Group in the Department of Mechanical Engineering at Imperial College London. It will be supervised by members of academic staff in the Group including Prof. Daniele Dini, Dr Janet Wong and Prof. Hugh Spikes. The studentship is for 4 years starting in October 2024 and will provide full coverage of standard tuition fees and an annual tax-free stipend of approximately £24,000. This studentship is funded by an EPSRC Industrial Cooperative Awards in Science & Technology (CASE) and industrial partner Shell.  The student will be expected to study at a Shell location for a minimum period of at least 3 months during the studentship and will be offered industrial mentoring throughout the project. At Imperial, the student will be a member of a larger community of Shell-funded researchers in the Tribology Group who are working on lubricants and electric vehicle-related projects, which cover both experimental and modelling techniques across the scales. The Tribology Group at Imperial College is a vibrant, world-leading research group with unparalleled experimental and modelling equipment facilities.

The project is concerned with the development of novel water-based lubricants for EVs and environmentally-friendly hydraulics. The aim of this project is to improve our understanding of and ability to design aqueous lubricants based on polymer solutions in water. Although most liquid lubricants are based on organic hydrocarbons and esters, for many years a few have been based on water.  To date these have been used primarily as mining hydraulic fluids (because of their fire resistance) and in metal cutting (due to their superior cooling properties).  However, there is now growing interest in using water-based lubricants in a much wider range of applications, including electric vehicle (EV) transmissions, industrial oils and hydraulics. Their excellent cooling properties are important for EVs, but the main desirable features in other applications are their biodegradability and general green credentials.

The main objectives of this project are to study the fundamental aspects that govern the performance of water-based polymer solutions as lubricants. This will be pursued by looking at novel sustainable formulations of polymers to be used to form separating films with characteristics similar to those achieved with the best performing conventional lubricants.  We will be adopting our modern experimental techniques, which include very high shear rate viscometry, film thickness measurement rigs and conventional rolling-sliding tribometers as well as in-contact fluorescence to explore the in-contact composition of lubricant films and local viscosity and rheological description of the fluids under consideration.  This will be coupled with the use of in-house models that can be employed to explore and predict the behaviour of newly developed fluids in different components and applications of interest to Shell.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You should hold or expect to obtain a First-Class Honours or a high 2:1 degree at Master’s level (or equivalent) in Mechanical Engineering, another branch of relevant engineering, Materials, Physics, Chemistry or a related science. We expect you to have an enquiring and rigorous approach to research together with a strong intellect and disciplined work habits. An interest in developing new experimental and/or modelling techniques for the discovery of new engineering solutions for the energy transition is essential, as are good team-working, observational and communication skills.

Applications are invited for a research studentship in the field of “Next Generation Patterned Steel Floors for Best in Class Slip Resistance Performance”, leading to the award of a PhD degree. The studentship will be based in the Tribology and the Metal Forming and Materials Modelling groups in the Department of Mechanical Engineering at Imperial College London. It will be supervised by Prof. Daniele Dini and Professor Jianguo Lin as well as an industrial expert, Dr Bin Xiao from Tata Steel. The studentship is for 4 years starting in October 2024 and will provide full coverage of standard tuition fees and an annual tax-free stipend of approximately £24,000. This studentship is funded by an EPSRC Industrial Cooperative Awards in Science & Technology (CASE) and industrial partner Tata Steel UK.  The Tribology and the Metal Forming and Materials Modelling groups are vibrant, world-leading research groups with unparalleled experimental and modelling equipment facilities.

It is well known that slips and trips are the most common cause of injuries at work and therefore subject to Health and Safety Executive (HSE) consideration. Tata Steel UK is a product leader in the UK market for patterned steel floor plates. The dense pattern of studs on as rolled steel floor plates can provide outstanding slip resistance in both dry and wet conditions at all angles and allows plates/thick strips to be used in any direction. They are typically used in stairways (good bendability), walkways, lifts, platforms and bridges, and offering superior slip resistance. However, the fundamental mechanisms and important factors (stud geometry, roughness, conformance to shoe sole standards,…etc.) determining slip resistance under different conditions are not well understood; lack of fundamental knowledge hinders the development of new disruptive solutions in this space.

The main objectives of this project are to determine and rank important parameters controlling slip resistance of floorplate, as well as generate novel pattern designs with enhanced slip resistance performance. This will be achieved by combining fundamental understanding of tribological interactions and innovative surfaces and materials design and processes. The main outcome of this research programme will be the development of tools and methods for the selection of new geometrical patterns that could be considered for the next generation of patterned steel floor plates. This technology will also be applied to other Tata Steel UK products that require enhance slip &/or wear resistance performance. We will target the development of new geometrical patterns for products for specific applications through the development of advanced physics- and data-driven models, as well as laboratory tests and current industrial standards for validation. This will lead to new design tools and standard of broad applicability.

Applications are invited for a research studentship in the field of fluid dynamics, leading to the award of a PhD degree.  The post is supported by a bursary and fees (at the UK student rate) provided by the EPSRC through an iCASE studentship with Siemens Energy. Candidates must demonstrate relevant connection with the UK, usually established by residence, as is standard for EPSRC funding. 

Thermoacoustic instability is caused by a two-way coupling between acoustics waves and unsteady combustion. It can occur in the combustors of gas turbines and leads to damaging high amplitude oscillations. The need to decarbonize energy generation is driving the transition to hydrogen as a fuel. However, hydrogen enrichment increases propensity to thermoacoustic instability. In order to design-out thermoacoustic instability, accurate and efficient methods for its computational prediction are needed. Multi-scale computations, which couple different treatments for the acoustic waves and the flame, are particularly efficient. The acoustic waves are captured using linear, wave-based models, while the flame unsteadiness is obtained using computational fluid dynamics in the form of large eddy simulations (LES). These coupled approaches have been applied with success to predict thermoacoustic instability in real combustors, but not as yet for hydrogen-rich combustors.

This PhD will work towards this in two key ways. Firstly, to deal with hydrogen’s vastly different properties – its fast flame speed, low density, high diffusivity etc - compared to traditional fuels, the best flame simulation tools for thermoacoustic predictions will be investigated. Secondly, for the largest, most efficient gas turbines, combustion occurs in separate but linked “cans”. New acoustic models will be developed for multiple cans interacting at their downstream end.

The project will combine mathematical modelling and flow simulations for hydrogen combustion, the latter using the OpenFOAM CFD package. Machine learning will be used to model the effect of hydrogen enrichment on the flame. The project will work towards fully computational prediction of thermoacoustic instability in an experimental hydrogen-rich lab combustor (at a collaborator’s lab) which can operate in single-can, two-can and three-can modes.

You will be an enthusiastic and self-motivated person who meets the academic requirements for enrolment for the PhD degree at Imperial College London. You will have a 1st class honours degree in mechanical engineering or related subject and demonstrate excellent project-work and communication skills. You will be interested in fluid dynamics, acoustics and computational fluid dynamics. You will join a supportive and inclusive research group and benefit from co-supervision with the Siemens Energy partner.
