Oliver Buxton is a Reader in Experimental Fluid Mechanics in the Department of Aeronautics at Imperial College London. The main focus of his research is the application of laser diagnostics to turbulence research. In particular, he has focused on multiscale-generated turbulence and turbulent entrainment, specifically turbulent entrainment from a turbulent background. He is currently an EPSRC fellow applying these advances to understanding, and modelling turbulent wakes produced by wind turbines which is a vital precurosr to developing accurate wind-farm optimisation tools.
Another of his interests is cloud microphysics. In particular he is interested in exploring the nature of the turbulent/turbulent entrainment physics for warm cumulus clouds as well as the interaction between cloud-turbulence and water droplets. He has secured ERC funding for this purpose running from 2024 - 2029.
He also has a developing interest in Martian aerodynamics. Due to the thin atmosphere, and different chemical composition (primarily carbon dioxide), flight on Mars is characterised by a peculiar combination of transonic Mach number and very low Reynolds number (typical of insect flight on Earth).
