Research Description: Experimental fluid dynamics focusing on flow control and aeroacoustics. Current projects include a grazing flow impedance facility for acoustic liners, aeroacoustic measurement technology, acoustics and fluid dynamics of circulation control airfoils, aircraft landing gear noise, development of advanced zero-net mass-flux actuators for active flow control applications, active flow control of wing tip vortices, flow separation, cavity oscillations, and flow over 3-D turrets for directed energy applications.

PIRE Project Description: The goal of the research is to understand the nonlinear dynamics of separated flow and to develop effective control techniques that exploit those dynamics. Previous studies have shown that separated flow is dominated by nonlinear interactions between the shear layer, separation bubble, and wake dynamics.  In this work, we will explore appropriate nonlinear modeling, estimation, and nonlinear control methods. Special emphasis will be placed on efficiently producing large excursions in phase space intended to move the flow between distinct states. This work will be conducted in collaboration with Drs. Bernd Noack and Laurent Cordier at  l’Université de Poitiers, Prof. Mittal from Johns Hopkins University , Prof. Clancy Rowley from Princeton University, and others here at the University of Florida .
