Undertakes mainly applied research that relates to current and future gas turbine engines. This includes purely aerodynamic and fluid mechanic fundamental studies of the flows found within various gas turbine components (e.g. diffusing flows, wake mixing separated flows, streamline curvature, highly swirling flows), through to investigations of flows within more complex engine representative environments. In addition, work is conducted in multi-disciplinary areas where the aerodynamic flow field strongly interacts with influences other processes. This includes aerodynamics and two phase flows (sprays), aero acoustics, combustion instabilities and heat transfer.
