On the Flow Physics of Effectively Controlled Open Cavity Flows
Abstract
The intense aeroacoustic environment of flow over open cavities is created by an important fundamental flow phenomena associated with a resonating fluid system. In practical applications, this resonating flow can be extremely detrimental to aircraft due to the creation of high levels of broadband and tonal fluctuating pressures. The ability to alter flow field characteristics for a practical advantage represents a significant challenge that, when accomplished, can lead to paradigm shift in how systems involving fluid flow are designed. The research reported in this document represents accomplishments on controlling the flow over open cavities and developing a better understanding on how leading edge actuation alters the flow. The two focuses of this research, detailed flow measurements of successful active control strategies and development of adaptive control strategies, have both advanced the knowledge active as applied to high speed flow over open cavities. On the flow measurement side, we have explored the evolution of flow downstream of segmented leading edge blowing slots.
