Research Interests

Voice Production

Investigate the fundamental aerodynamic mechanisms of voice production using dynamic physical models, and numerical simulations (CFD). http://widget.ecn.purdue.edu/~voice/

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

Identify and investigate potential applications of thermoacoustic refrigeration and/or air-conditioning. Develop system optimization tools. Design and build working prototype. Model validation, and investigation of unexplained physical phenomena. http://widget.ecn.purdue.edu/~thermacs/

Turbo-Machinery Noise

Develop experimental methods for the identification of potential sound generating phenomena in turbomachines (liquid pumps, cooling fans, compressors, ...).

Control of Flow-Induced Sound and Vibrations

Understand and control aerodynamically generated sound and vibrations. Develop methods for modeling the noise emissions of flow-excited structures. Active control of flow-induced noise using flow manipulators. High frequency energy models for structural noise emissions.
