Abstract
There has been a surge in the development of feedback flow control technologies in recent years. Regardless of what method is used to design the controller, the input signal to the controller in any application must come from surface measurements and in most cases surface pressure measurements. Therefore, there is a strong need to understand and establish correlations between surface pressure fluctuations and flow field properties (e.g. flow velocity). The main objective of this Phase I proposal is to establish such correlation in a generic weapon bay cavity, where there is a need for suppression of strong pressure fluctuations due to coupling of flow and acoustics within the cavity. ISSI and OSU have significant expertise in cavity flows and development of reduced order model based feedback control for cavity flows. The work has been carried out in low speed cavity flows and significant expertise has been developed in correlating surface pressure fluctuations and flow field properties. And these correlations have been used in successful design and implementation of feedback control in low speed cavity flows. In Phase I the effort will be focused on extending this expertise to high subsonic and supersonic flows.
