Ben Thornber is currently researching Large Eddy Simulation methods for complex, highly under-resolved industrial flows and compressible turbulent mixing including combustion. The focus is on the development of turbulence modelling and high resolution upwind algorithms specifically designed for large eddy simulation of multi-component turbulent flows at all Mach numbers and their application in complex geometries.
Dr Ben Thornber is a Lecturer in the Department o fEngineering Physics. He completed his PhD at Cranfield University investigating and significantly improving the performance of high resolution methods to investigate the physics of shock induced turbulent mixing. This was selected as the best UK PhD research in the field of flow, turbulence and combustion (2009 ERCOFTAC Osborne Reynolds award). His specialisation is in the development of massively parallel computational fluid dynamics methods capable of simulating high Reynolds number compressible flows in complex geometries. This includes the theoretical and numerical analysis of very high order accurate methods, large-eddy simulation of multi-species flows including combustion, shock physics, fundamental instabilities and transition, theory and modelling of turbulent mixing, flows with massive separation at high Reynolds number, computational aero-acoustics, parallelisation techniques, and high performance computing.
This work has resulted in publications in high impact factor journals such as the Journal of Fluid Mechanics, Journal of Computational Physics, Computers and Fluids, AIAA Journal, International Journal of Numerical Methods in Fluids, Aeronautical Journal and the Journal of Fluids Engineering. He has worked on industrial projects with AWE, NASA Jet Propulsion Laboratory, European Space Research and Technology Centre (ESTEC), AMPAC-ISP, MBDA, MOD and SEA.
