Flow control device, flow profile body and flow influencing method with acoustic wave generation

摘要

For adaptively influencing a flow with little intrusion into the surface, a flow control device is provided to influence the flow of a fluid medium on a fluid-dynamical surface of a fluid-dynamical profile body. An acoustic wave generating device is used to generate a standing acoustic wave with locally defined antinodes and nodes, and/or a sonic pulse is focused in a locally defined manner.
