Experimental Study of Adaptive Control of High-Speed Flow-Induced Cavity Oscillations

Experimental Study of Adaptive Control of High-Speed Flow-Induced Cavity Oscillations

This paper describes progress towards the development of an active suppression system for open cavity oscillations. A leading-edge array of piezoelectric zero-net mass-flux (ZNMF) actuators is used to suppress cavity flow oscillations determined from measured pressure fluctuations near the rear wall...
