Research
The main research areas of the Aerodynamics Group at the University of Bath are unsteady aerodynamics and vortex-dominated flows. Professor Gursul’s research group has authored around 150 journal and conference papers. These include recent survey articles on unsteady vortex flows in Progress in Aerospace Sciences and Journal of Aircraft.
The Group’s work includes unsteady aerodynamics of aerofoils and wings in unsteady free stream, delta wing aerodynamics, buffeting and vortex breakdown, aircraft vortex wakes, flow control and synthetic jets, low Reynolds number aerodynamics, and fluid-structure interactions.
Current activities include unsteady aerodynamics of manoeuvring wings, low Reynolds number aerodynamics, flow-structure interactions on low aspect ratio wings, unsteady aerodynamics of membrane wings, and flexible oscillating foils near a free surface.
Recent research has been funded by EPSRC (GR/R07738/01, GR/S59383/01, EP/C015258/01, EP/F026099/1, the RCUK Academic Fellowship in Unmanned Air Vehicles), the US Air Force Office of Scientific Research (AFOSR) (F61775-02-C4024, FA8655-06-1-3058, FA8655-07-1-3044, FA8655-10-1-3093), the US Office of Naval Research (ONR) (N62909-10-1-7117), EC 6th Framework (FAR-WAKE), and industry (Qinetiq, BAE Systems, DERA).
