The intense fluctuating pressures observed in open cavities are extremely detrimental hence the ability to control the flow to minimize them is an important challenge. Many open loop methodologies have proven effective at this for single operating conditions, however they often are detrimental at off design conditions. Closed loop flow control is applicable over a range of flow conditions and is the thrust of many current and past studies. However in order to advance its effectiveness there is a need for a better understanding of the flow physics and the effect that control has on it. This study represents a step in the direction of developing the tools that will allow for a better understanding of this flow physics along with an improvement adaptive control methodologies.
