Professor Vahdati is the Principal Research Fellow in the Dynamics Group, and leads the Aeroelasticity Group in the Vibration University Technology Centre sponsored by Rolls-Royce plc.

His main research focus is the development of CFD algorithms, modelling fan blade flutter, turbine and compressor forced response, stall and surge modelling, and aeroacoustic and aeroelastic phenomena. In practice,one of the main reasons for turbomachinery failure is vibration, and our work is directly relevant to industry.

Through modelling the behaviour and mitigating causes of engine failures, leads to substantial increases in safety and reliability, provides energy-efficient environmental friendly benefits and major costs savings.

Research Activities
• Development of CFD algorithms for the efficient numerical modelling of both internal and external flows.
• Fan and compressor blade flutter.
• Compressor forced response
• Simulation of one-off events, such as bird strike, blocked compressor vane.
• Stall and surge modelling in compressors.
• Prediction of aero-engine noise
• Development of low order models for use during design stage• Aeroelastic behaviour of wind turbines.
