Control effect of a synthetic jet actuator on boundary layer flow under adverse pressure gradient

Project Member(s): Gaston, M.

Start year: 2001

Summary: Flow separation or transition to turbulence in a boundary layer degrades the performance of aerodynamic devices such as compressors and aircraft, and causes unstable conditions and noise around buildings and road vehicles. Traditional flow control only works under restricted conditions. Active control using synthetic jets has recently been recognized as a promising manner for boundary layer flow control. This project aims to identify the effect of synthetic jets on flows under adverse pressure gradient and leading to separation or turbulence. The outcome will be a design method for active controllers which not only prevent separation, but also minimize the friction loss and drag.
