His main research interests are:
- Development of CFD algorithms for the efficient numerical modelling of both internal and external flows.
- Fan blade flutter. Explanation of two predominant fan blade flutter mechanisms, namely aero-acoustic flutter and separated flow flutter.
- Compressor forced response. Both inlet distortions and blade-passing wakes create significant unsteady aerodynamic forcing on the rotor blades.
- Turbine forced response. The unsteady aerodynamic forcing is either due to blade passing excitation, or to low engine-order harmonics due to some loss of symmetry in the flow.
- Simulation of one-off events, such as bird strike, blocked compressor vane.
- Stall and surge modelling in compressors. The flow at these conditions is characterised by partial or total reversal of the flow such events can cause enormous vibratory stresses on the blades which may result in engine failure or shut down.
- Aeroelastic behaviour of wind turbines. As the size of wind turbines increase to allow for larger energy capture, they will be subject to greater risks of aeroelastic fatigue failure and extreme loading events.
