The research of the Unsteady Fluid Dynamics Group sits in the broad areas of fluid dynamics, turbulence and aeroacoustics with a concentration on elucidating flow physics associated with certain engineering properties (drag, noise generation, unsteady forces, etc…) so that they can be altered for an engineering benefit.
Cavity Flows
- Elucidation of sources of surface pressure fluctuations in open cavities
- Open-loop control of cavity pressure fluctuations with leading edge blowing
- Closed-loop control of cavity pressure fluctuations

Fluid Structure Interactions with Meta-Materials
- Shock boundary layer interaction with vibratory meta-materials
- Physical reservoir computing of shock boundary layer interactions

Flow Generated Noise
- Identification of turbulent noise sources in transonic jets
- Control of noise generation from supersonic jets
- Identification of turbulent flow noise sources from turbulent wall jets and circulation control airfoils
- Rotor noise for Urban Air Vehicles
