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, (http://users.complexity-coventry.org/~potherat/), 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 (http://www.leverhulme.ac.uk). 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. The Research Associate will work within the vibrant environment of the Fluid Dynamics group, part of the Fluid and Complex Systems Research Centre, at Coventry University. The group conducts both fundamental and applied research in the fields of stability, magnetohydrodynamics, turbulence and geophysical fluid dynamics as well as other areas of fluid mechanics. In the REF2014, 84% of the group’s output, as part of the mathematics submission, was deemed ‘internationally excellent’ or ‘world-leading’. The project involves extended stays at the Grenoble High Magnetic Field Laboratory, France where the experiment will be operated.

The post is fixed term until 31st December 2021. To apply please also include your CV with a publication list. For further information please contact Professor Alban Pothérat (Coventry University, alban.potherat@coventry.ac.uk, +44(0)2477 65 88 65).

Research Fellow position in theoretical fluid mechanics at Coventry University (UK)

Coventry University

Location: Coventry Placed On: 2nd August 2019
Salary: £32,243 to £40,802 per annum Closes: 2nd September 2019
Hours: Full Time Job Ref: REQ007193
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 (http://www.leverhulme.ac.uk), 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 (http://users.complexity-coventry.org/~potherat/index.html) 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. This unit is part of the Fluid and Complex Systems Research Centre, and specialises in theoretical and experimental fluid mechanics. It is especially renowned for its work on magnetohydrodynamics (MHD), turbulence, stability and geophysical flows. The group closely collaborates with partner groups in world-leading institutions in Australia, China, France, Germany and the UK.

Informal enquiries are welcome: please forward a CV and academic records to Prof. Alban Pothérat (alban.potherat@coventry.ac.uk).
