| Outline of Final Research Achievements |
The purpose of the research is to study the flow structure induced by a combined type of actuator which is composed of a synthetic jet and fixed vortex generator and to develop the combined type actuator for flow control. The synthetic jet and plasma jet actuators promote the flow mixing and prevents flow separation, because it introduces a periodic disturbance which is more effective for the flow separation control. The fixed vortex generator provides with a longitudinal vortex structure with a common flow down motion. The vortex structure downstream of the combined actuator was measured by a scanning stereo-scopic particle image velocimetry. The experiments on the different kinds of the actuator and the combined type actuator were conducted in the two dimensional channel flow, the circular impingement jet and the backward facing step flow. Then, it is found that the combined actuator introduces an effective vortex structure for flow control and the improvement of the heat transfer.
