Recent Progress in Closed-Loop Control of Cavity Tones
Active flow control of cavity tones has been successful in controlling Rossiter tones in both subsonic and supersonic flows. While closed-loop control promises the lowest actuator power requirements and the ability to adapt to changing flow conditions, so far it has only been demonstrated on subsonic cavities. Suppression of Rossiter tones in supersonic cavities has been demonstrated using open...
متن کاملAn Experimental Investigation of Cavity Flow
Understanding and controlling the flowfield in and around a cavity has challenged researchers for a number of years. The presence of a cavity on a body has been observed to significantly increase the mean drag, cause flow-induced vibrations and give rise to strong acoustic production. Of particular interest here are the flow structure and dynamics associated with open shallow rectangular caviti...

متن کاملAn Experimental Study of the Cavity Flow for Closed-Loop Flow Control
We present the results of an experimental investigation conducted as part of a multidisciplinary effort intended to address systematically the problem of closed-loop flow control by assembling expertise from numerical and experimental flow analysis, flow modeling, and control design disciplines. Experiments were conducted using a shallow-cavity flow in a small-scale wind tunnel that can operate...
متن کاملExtremum-Seeking Control of Subsonic Cavity Flow
An adaptive control system using extremum-seeking optimization is developed to suppress subsonic cavity flow oscillations. The overall control system is developed by following two steps. First, a simple linear control law which uses measurements of wall pressure fluctuations at two different locations in the cavity is developed, and the effect on the magnitude of the limit cycle produced by tun...
