| Research Abstract |
The effort for performance improvement of the active dimple and plasma actuator was conducted. The appropriate parameters such as frequency, dimple depth and Reynolds number range resulting in the effective development of the separating shear layer were obtained, when the active dimple was applied to the separated diffuser flow. The vortex structures of the synthetic jet which depended on the injection conditions were also clarified when the jet was injected into the quiescent fluid or the cross flow. The characteristics table of different kinds of actuator which showed the benefit and deficit of the actuator depending on the operating conditions was obtained.
