Event details

ISVR Engineering Research Seminar Series

Aerodynamic noise radiated from industrial fan blades has been receiving much attention from the civil aircraft, wind turbine, turbomachinary, automobiles and home appliances industries. In many cases, the aeroacoustic behaviour of an aerofoil depends on the boundary layer development over its lifting surfaces, and/or the development of wake downstream. The application of active or passive flow control technique to alter these hydrodynamic features, and to achieve aerofoil noise reduction, has already been demonstrated by many. However, and perhaps ironically, the application of some of these flow control techniques can actually result in a poorer aerodynamic performance. This seminar will discuss some of the active and passive flow control techniques for the reduction of aerofoil noise, and their challenges and further opportunities.        

Speaker information

Tze Pei Chong, Senior Lecturer at Brunel University London. Tze Pei Chong is a senior lecturer at Brunel University London. Before that, he was a postdoctoral research fellow working with Professor Phillip Joseph at ISVR University of Southampton on experimental study of aerofoil noise. He obtained his PhD at University of Manchester on the topic of boundary layer transition on non-isothermal condition. For his undergraduate degree, he studied Aerospace Engineering at the nearby UMIST (now absorbed by the UoM).
