Applications are invited for the position of Research Fellow in theoretical and numerical fluid mechanics sponsored by the Engineering and Physical Sciences Research Council. The successful applicant will work under the supervision of Dr Junho Park and Prof. Alban Potherat on nonlinear stability and turbulence modelling in two specific problems.
The first problem aims at Modelling turbulence induced by hydrodynamic instability in differentially-rotating flows. The project will investigate theoretically and numerically the nonlinear development of centrifugal instability in differentially-rotating flow and develop a new turbulence model for multi-physics simulations. The project will advance our understanding of instability-driven turbulence and its role in multi-physics processes, for instance, those in the evolution of stars.
The second problem will consist in seeking the nonlinear states of convection in vessels heated from below and cooled from the top (Rayleigh-Bénard problem) in cases where the boundaries are not simple planes, and when the flow is subject to magnetic fields and background rotation. The question is whether convection can set in subcritically, ie, for lower critical temperature differences than predicted by the standard Rayleigh-Bénard theory. The answer could bring a new understanding of how planets sustain their magnetic fields but also advance our understanding of processes taking place in alloy casting.

It is expected that the successful candidate will have a deep understanding of fundamental fluid dynamics such as hydrodynamic stability, convection, turbulence, or rotating flows, and advanced knowledge of geophysical and astrophysical fluid dynamics and nonlinear systems in general. Experience with high-performance numerical simulations such as direct numerical simulation (DNS) or large-eddy simulation (LES), or in branch tracing techniques would be an advantage. In addition, the successful candidate should also be experienced in applying relevant numerical methods using MATLAB, Fortran, Python, Fortran or C++ (or similar).

The successful candidate should hold a PhD or equivalent in Fluid Mechanics or a related subject with a proven track record of producing scientific output at the highest level, as evidenced by high-quality journal publications. The Research Fellow 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 REF2021, 95% of the group’s output, as part of the mathematics submission, was deemed ‘internationally excellent’ or ‘world-leading’.

The successful candidate’s academic development will be supported through Coventry University’s Early Career Researcher support programmes, alongside other researcher development activities. Given the importance of public engagement activities to this project, they will be given the opportunity to complete a Media Training Skills course.
