Research Interests

Voice Production

Investigation of the fundamental aerodynamic mechanisms of voice production using dynamic physical models and numerical simulations (i.e., computational fluid dynamics). 

Aerodynamic Noise in Vehicles

Sound generation from flow aspiration through automobile and aircraft sealing systems and structural sound transmission through rubber seals. Measurement, modeling and control of self-sustained flow oscillations produced by flow grazing over open cavities. Applications include automobile windows and sunroofs.

Thermoacoustic Refrigeration

Identification and investigation of potential applications of thermoacoustic refrigeration and/or air-conditioning. Development of system optimization tools. Design and construction of a working prototype. Model validation and investigation of unexplained physical phenomena.

Turbomachinery Noise

Development of experimental methods for identifying potential sound generating phenomena in turbomachines (e.g., liquid pumps, cooling fans and compressors).

Control of Flow-Induced Sound and Vibrations

Seeking to understand and control aerodynamically generated sound and vibrations. Development of methods for modeling noise emissions of flow-excited structures. Active control of flow-induced noise using flow manipulators. High-frequency energy models for structural noise emissions.
