Turbulence and Aeroacoustics group  

Our group focuses on the sustainable development of modern transportation and energy systems. The overarching question my research group seeks to answer is how the structure of turbulent shear flows dictates drag, noise, and their propagation. My lab's mission is to reduce the noise and carbon footprint of modern transportation and energy systems while improving reliability issues linked to flow-induced vibration.

We use variety of experimental, numerical and analytical tools to study generation, propagation, and scattering of sound waves. 

Aeroacoustics.

 Aero+Acoustics is a branch of science that deals with noise generation via unsteady aerodynamics.

How is noise generated ?

In a vortex both centrifulgal forces (due to rotation) and pressure forces balance each other. However, any distortion or stretching of  vortex will break this "balance" and induce corresponding pressure disturbances that can propagate as far-field noise.
