报告内容摘要:

The plasma flow control technique is becoming one of the most promising methods because of its simple structure, fast response, no moving mechanical parts and so on. The comprehensive studies of the plasma flow control technique have been conducted including the actuators design, basic characteristics of the actuators, flow control mechanism and applications in flow control. The present work mainly discusses the dielectrical barrier discharge (DBD) plasma actuators. The induced flow fields, the effects of structure parameters and power sources on induced flow fields are studied by experimental tests and simulations. The results show that the structure parameters and power sources can induce different flow fields. Then the application of DBD plasma in flow separation control is studied in detail. It is interesting that the flow control mechanism may be different at different free stream velocities. The flow control mechanism should be studied further more especially at high-speed flow.
