Abstract:

An air supplementing type plasma synthetic jet (ASPSJ) generator has been developed in this paper. A one-way check valve, increasing the air refill supply at the recover stage, is connected to a typical spark discharge plasma synthetic jet (PSJ) generator. The ASPSJ improves jet flow continuity of typical PSJ and can get higher energy synthetic jet. The effect of different valves on the maximum average jet flow speed is researched with different electric parameters. The best electric parameters for the highest synthetic jet flow speed are obtained by orthogonal test. For the test ASPSJ generators, the best loading voltage frequency, amplitude, and duty cycle are 150 Hz, 50 kV and 15%. The results show that ASPSJ strengthens the maximum average jet flow speed by above 20%. The best actuation frequency is increased, and the actuation frequency bandwidth for maximum jet flow speed enlarges from one point to 100 Hz. Better airflow control effect can be expected by ASPSJ in wind tunnel tests. The research results provide guidance for further active flow control application.
