Abstract
Development of a surface measurements based active feedback flow control strategy for cavity flow fields is proposed. The method relies on the estimation of flow field characteristics using surface pressure measurement. The estimated flow field will be used by a controller to provide suitable actuation to the flow filed to effect control. The actuation requirements will be identified through analysis of existing datasets (computational and experimental). A numerical test bed will be implemented to test this overall strategy and to identify controller requirements. The Phase I part of the program will explore development and refinement of a lower dynamical model, exploration of existing datasets to identify actuation requirements and feasibility testing on a numerical test bed. Phase II part of the program will refine/develop actuators, address controller design and conduct experimental testing at a suitable scale. It is envisioned that the successful completion of this effort will not only achieve a better understanding of the complex phenomenon of flow induced cavity oscillations with and without control, but also result in the development of technology applicable to store separation from internal weapons bays at supersonic speeds.
