ABSTRAKT

The paper presents an experimental study of a flow control of a turbulent plane mixing layer by normal synthetic jets deployed through an array of circular orifices. The experimental configuration represents a flow control strategy for deflecting a mixing layer which has application in the control of separated flows. The mean and turbulent fields have been investigated. The control jet interacts with the mixing layer and modifies its turbulent energy behaviour. It is observed that the more important effect is the enhancement of the mixing properties of the mixing layer when controlled. This effect creates a deflection of the mixing layer toward the wall.
