Description of the research problem:

Context and challenges

In the MATIM laboratory, we carry out fundamental and application-oriented research related to energy and environmental aspects in different research fields.

The SURFMED project is part of a program which aims to develop innovative functionalized surfaces by magneto-electrochemical methods and to investigate their performance and resistance to aging for electro and magneto wetting applications. The final application is aimed at increasing heat transfer at the millimeter scale.

Magneto-electrochemistry is used in this project to design super-hydrophobic patterns, especially for electro-wetting studies, with good permittivity control at the micro-scale of the deposit.

Scientific objectives

– Synthesis of formed coatings and understanding of nucleation and growth mechanisms under the effect of forces induced by magnetic fields. characterization (physico-chemical and electrochemical);

– Modeling of electrochemical processes considering magnetohydrodynamic flows;

– Determination of process – structure – property relationships through a multi-scale and interdisciplinary approach. The specific properties sought relate to the intended objective, namely the optimization of the cooling regimes;

– Evaluation of the durability of these coatings under operating conditions and study of their resistance to corrosion by electrochemical methods.

Methodology and implementation techniques

A first part will consist in defining the parameters necessary to obtain well-structured alloy coating morphologies and the analysis of the reactions involved. Parameters such as electrolyte compositions, temperature during electrodeposition, current densities, potential, pulsed mode deposition parameters will be defined. This task will include the study of nucleation and growth mechanisms by analyzing electrochemical curves and modelling the influence of MHD and µMHD forces.

A second part will include the morphological and structural characterization by SEM and XRD of the synthesized coatings and the roughness will be determined.

The surface properties of alloy coatings are important in determining the durability and aging of a deposit. Zeta potential measurements of the alloy coating will be performed to determine surface charge as a function of various synthesis parameters to optimize wettability. The anti-corrosion properties of the coatings will be analyzed in an environment similar to their intended end use by measurements of corrosion potential, electrochemical impedance spectroscopy and physical analysis.



Profile and required skills:


Engineer and/or master level – Good level of general and scientific knowledge. Good level of oral and written French and/or English. Good analytical, synthesis, innovation and communication skills. Qualities of adaptability and creativity. Motivation for research activity. Prerequisites (specific skills for this PhD thesis): Good knowledge of chemistry in general and solid-state physico-chemistry in particular.

Postdoctoral Position in Numerical Simulation of Radiative-MHD

(from Prof. Ben-Wen Li, Dalian, China)


The group of Prof. Dr. Li Ben-Wen, in Institute of Thermal Engineering, School of Energy & Power Engineering, Dalian University of Technology (DUT), has a long time and wide experience in researching thermal radiation, and its combinations with others, like, conduction, convection, combustion, and magnetohydrodynamics (MHD), and especially engaging in the numerical simulation. Recently, we obtained the NSFC (National Natural Science Foundation of China) project, titled “Research of Thermal Radiation Effects on Magnetohydrodynamics Instabilities” with granted No. 51976021 (Jan. 2020 till Dec. 2023). We are applying for more projects. We have accumulated lots of home-designed codes for pure thermal radiation (with participating media in 3D Cartesian coordinate systems and 2D cylindrical ones), radiation-conduction, radiation-hydrodynamics and radiation-MHD (spectral methods but with limitation of laminar flow). Meanwhile, lots of journal papers have been published. Based on the NSFC project, we are preparing experimental research and also numerical simulations, especially for laminar to turbulent transition. In such cases, a full postdoc position for the experienced scholar, who is an expert in CFD with DNS, is available.

The main task of the postdoc will be the numerical simulations of transition or turbulent Radiative-MHD in a cylinder or rectangular enclosure. The numerical methods can be the Finite Difference method, the Finite Volume method, but the Spectral method will be a priority. At present, the MHD will be limited to quasi-steady cases (the magnetic Reynolds number is far less than unit). For thermal radiation, we expect the full RTE (radiation transfer equation) solution with help of Prof. Li Ben-Wen (many home hold codes using spectral methods). The main challenges may exist in the transition to the spectral code from MMT (matrix multiplication transition) versions to FCT/FFT (fast cosine transformation/fast Fourier transformation) versions, the turbulent radiation interaction (TRI), and the instabilities analysis. The code transition is necessary to reduce computer costs for instabilities and turbulent flow. The spectral methods are necessary to keep the higher accuracy. Based on the simulations, more phenomena/disciplines can be observed/discovered for radiative MHD.
Based on our former works, you will be supervised by Prof. Li Ben-Wen, and collaborating with Ph.D. students. You can guide Ph.D. students both in experiments and simulations, especially the DNS and instability analysis. Your creativity is welcome and expected during the research process.

As for thermal radiation, we have accumulated lots of codes based on spectral methods or discrete ordinates methods (DOM).
Work office and personal computer are provided. The computer center will provide a computation source for large computation, and the computation cost will be paid from the project.
The salary per year is ¥300,000RMB before tax, about $46,470. Our university can provide an apartment with a bath and cook, but cheap rent.
Dalian is the most beautiful city in north-eastern China, and the communications in domestic and international are very fast and convenient.

The candidate should have a PhD degree in Physics or Engineering (or equivalent), with demonstrated experience in CFD in fluid mechanics, or thermo-hydrodynamics, or even in MHD.

We offer the open, stimulating and multi-disciplinary research environment. The duration of the contract will be 2 years. After evaluation, it will be possible to extend another 1 year.

PhD on the Transition to Turbulence in Particulate Pipe Flows (Coventry, UK)

A PhD position in experimental fluid mechanics is open at the Centre for Fluid and Complex Systems (FCS), Coventry University, in collaboration with Oxford University, under the joint supervision of Prof. Alban Pothérat, (Coventry University, UK, ) and Prof. Tom Mullin (Oxford University).

The topic concerns the experimental study of pipe flows seeded with particles. At high enough flowrates, flows of liquids in pipes become turbulent. The transition process involves complex nonlinear mechanisms that are still not fully understood. Yet predicting, delaying or triggering – in other words controlling –  the onset of turbulence is a pressing need both as one of the fundamental challenges of fluid mechanics and for the vast range of practical problems where the radically different energy and pressure losses incurred in laminar or turbulent flows have drastic consequences.

A more recent angle to this problem emerged with the growing practical importance of flows seeded with particles that can either prevent or induce a transition to turbulence depending on their size and concentration.  The underlying mechanisms were unknown until recently. The centre for Fluid and Complex systems developed a fully transparent pipe flow device of hitherto unmatched accuracy fitted with a unique optical detection device capable of mapping the motion of fluid and particles simultaneously to make the first breakthrough in this problem of fundamental importance. The question now is to understand how the motions of fluid and particles interact in detail, ultimately manipulate this interaction with electric fields and control the transition.  This is precisely the objective of this PhD, that offers a unique opportunity to use and develop cutting edge experimental techniques to tackle one of the great challenges of nonlinear physics, for both fundamental and practical purposes.

The fluid and Complex Systems Research Centre ( gathers fluid dynamicists, physicists and engineers to tackle fundamental, but also real-life problems involving fluids and complexity with mathematical rigour. For example, aside from its more traditional forte in fluid dynamics and statistical physics, the centre is also developing novel approaches in engineering fluid mechanics, flow measurement and socio-physics. The Fluid Dynamics Group currently comprises 15 Staff and PhD students and runs projects combining theory, numerical simulations and experiments, supported by a number of grants from research funding bodies (EPSRC, The Leverhulme Trust, the Royal Society…) and international partnerships. The group forms part of Coventry University’s Mathematics Unit of Assessment (10) for the Research Excellence Framework. 87% of the submission’s output was deemed internationally excellent at REF 2014. The centre prides itself in its active integration of PhD students in its academic life (events, seminars, interaction with its staff) and provides a vibrant international and interdisciplinary environment conducive to the production of world-class research.

Candidates must hold, or be on course for a 1st class Bsc. or Msc. degree in engineering or physics, with previous experimental experience and be motivated to conduct technically advanced experimental projects. Experience in fluid mechanics and/or measurement technology is strongly advised. The position is for a period of 3.5 years and is expected to start in January 2021.

To express interest in this PhD opportunity, please send a CV and a full transcript of academic records to Alban Pothérat (Coventry University, alban.potherat(at) Informal enquiries are encouraged.

Research Fellow in Experimental Fluid Mechanics on Magnetoconvection in the Earth Liquid Core Funded by The Leverhulme Trust

Full-time, Fixed Term until 31st December 2021
Closing Date: 13 March 2020
Under the supervision of Professor Alban Pothérat, (, Executive Director of the Centre for Fluid and Complex Systems Research, Coventry University, UK.

Applications are invited for the position of Research Associate in Experimental Fluid Mechanics sponsored by the Leverhulme Trust ( The project concerns convection in magnetic fields in the so called “Tangent Cylinder” region of the Earth’s core. Much of the mystery surrounding the Earth’s dynamics (its magnetic field, plate tectonics) lies in the nature of the convective patterns within the Earth’s liquid core, and in particular in the region called the “Tangent Cylinder”. What are the possible convective states under the combined influence of the Earth’s rotation and magnetic field, and how erratic are they? This project is part of a theoretical and experimental research program funded by the Trust that aims at answering these questions. The purpose of the experimental part of the programme is to explore the nonlinear convective states that may exist within a laboratory based ‘Tangent Cylinder’ when suitable perturbations are applied to the flow. These states will then be evaluated to see which are mostly likely to underpin the Earth’s core convection.

The project involves operating a novel experiment previously developed in our group to visualise rotating magnetoconvective patterns. Its principle is to use a weakly conductive, but transparent electrolyte, subjected to the very high magnetic fields available at the Grenoble High Magnetic Field Laboratory (France). Part of the experimental work will consist of upgrading the technique first developed in this experiment that makes it possible to visualise flow patterns in electrically conductive fluids by means of bespoke Particle Image Velocimetry (PIV) methods.

The successful candidate should hold a PhD or equivalent in Fluid Mechanics, Geophysics, or Physics with a proven track record of producing scientific output at the highest level, as evidenced by high-quality journal publications.

Contract Type: Permanent

A Research Fellow position in theoretical fluid mechanics is offered at Coventry University (UK). The project concerns convection under a magnetic field in the so called “tangent cylinder” region of the Earth’s core. Much of the mystery surrounding the Earth’s dynamics (its magnetic field, plate tectonics) lies in the nature of the convective patterns within the Earth’s liquid core, and in particular in the region called the “Tangent Cylinder”. What are the possible convective states under the combined influence of the Earth’s rotation and magnetic field, and how erratic are they? This study is part of a theoretical and experimental research program funded by the prestigious Leverhulme Trust (, that aims at answering these questions. The purpose of this thesis is to theoretically predict the possible nonlinear convective states for the first time. We will then evaluate which of these states are mostly likely to underpin the Earth’s core convection.

The Research Fellow will conduct the theoretical and numerical analysis of the problem under the joint supervision of Prof. Alban Pothérat ( and Dr Chris Pringle.  The study will seek the possible structure of convection by means of advanced stability theory and branch tracking method, to unveil the possible states. In the frame of the research programme, the work is purely theoretical/numerical and will be conducted in collaboration with an experimental study that will seek to reproduce and visualise these non-linear states in an experimental model of the Earth Core.

Successful candidates are expected to hold a PhD in fluid mechanics or a related discipline and to have demonstrated excellent abilities in mathematics and programming.

The successful candidate will be part the vibrant team of internationally recognised academics and PhD students forming the fluid dynamics group within the Applied Mathematics Research Centre, whose work has been ranked at 83% world-class at the UK’ latest Research Excellence Framework in 2014.
