The research of our team focuses on understanding and reducing noise generation from turbulent flows interacting with aero-structures, e.g. gas turbine engines, aircraft fuselage, aerofoils, wind turbine blades and other bluff bodies.

The Aeroacoustics group is part of the Aerodynamics and Environmental Flow group at the University of Surrey.

We investigate both fundamental and applied problems in aeroacoustics and fluid mechanics, using mainly theoretical and experimental as well as numerical methods. All these methods are being applied to specific engineering applications in order to understand the underlying physics of noise generation and develop new noise control techniques for civil aircraft, high-speed trains, automobiles, wind turbines, etc.

Experimental facilities available for research in aeroacoustics and fluid mechanics within the Aerodynamics and Environmental Flow laboratory include a newly built aeroacoustic wind tunnel (flow speed up to 35 m/s) and the closed-circuit Aero Tunnel (flow speed up to 40 m/s).

A fully automated testing instrumentation suite is equipped which includes multi-axis Particle Image Velocimetry (PIV), Laser Doppler Anemometry (LDA), hot wire anemometry, 6-component force balance, microphones, etc. The Surrey Phased Microphone Array system is currently under development which can be used to identify the locations and amplitudes of possible noise sources from any testing objects.
