Our Centre for Aerodynamics and Environmental Flow conducts world-class research in experimental and computational fluid dynamics, with a leading global output in computational fluid mechanics, environmental fluid mechanics, turbomachinery and wind energy. We also host the Environmental Flow (EnFlo) Atmospheric Wind Tunnel, which is part of both the Atmospheric Measurement and Observation Facility and the National Wind Tunnel Facility. It is the only wind tunnel in the UK capable of reproducing the speed, temperature and turbulence conditions in the Earth’s atmosphere. Our researchers also regularly collaborate with key players in industry, including QinetiQ, Rolls-Royce, the Defence Science and Technology Laboratory (Dstl) and Jaguar Land Rover. We also host the Rolls-Royce University Technology Centre in Thermo-Fluid Systems. In the Research Excellence Framework (REF) 2021, the University of Surrey ranks 15th in the UK for research power for engineering and top 20 in the UK for the overall quality of research outputs (research papers and other published works).
