Gas Turbine Noise
I am working on modelling and reducing gas turbine exhaust noise. The objective is to optimize the struts at the exhaust of the turbine for noise reduction. This project will use a combination of experimental, theoretical and numerical work in collaboration with the Whittle Lab. It is funded by Mitsubishi Heavy Industries.
Wind Turbine Noise and Open Rotor Noise
I have developed models for the prediction of wind turbine noise. For large wind turbines, the main source of noise is trailing edge noise. Trailing edge noise is generated when a turbulent gust reaches the trailing edge. Amiet has shown how to predict trailing edge noise for a fixed airfoil. He later extended his theory to predict trailing edge noise for rotating airfoils. However, there were disagreements on how to do this correctly. We have managed to resolve these disagreements and to show how to predict trailing edge noise for rotating airfoils.

I am exploring the physics of jet noise generation using direct numerical simulation and signal processing.
