摘要：

The paper presents an application of synthetic jets in the flow control of a jet. The synthetic jet actuator consists of an oscillating membrane operating at high frequency and separating two cavities with exit slots of different geometries. The synthetic jets work as an alternating push-pull system and the generated vortical structure changes the flow direction of the main jet (jet vectoring). The numerical investigations are performed using a RANS solver with an adequate turbulence model and demonstrates a changing of a jet direction.
