摘要:
为研究多电极等离子体合成射流激励器（ME-PSJA）的重频工作特性，实验使用微秒脉冲电源驱动ME-PSJA，实现了ME-PSJA的多脉冲工作模式。并通过电参数测量、高速纹影观测研究了不同激励频率下激励器的放电特性及流场特性。实验结果表明：ME-PSJA完整放电通道建立所需时间小于2 μs，实时响应频率大于
1400 Hz。当频率低于饱和频率时，提高频率可有效提高合成射流的时均动量与扩散范围，增强ME-PSJA的流动控制能力。当频率高于饱和频率时，ME-PSJA无法持续产生稳定射流，工作可靠性下降。-

Abstract:To investigate the repulsion characteristics of the multi-electrode plasma synthetic jet actuator (ME-PSJA), a microsecond pulse power supply was used to drive ME-PSJA, and the multi-pulse operating mode of ME-PSJA was realized. The discharge and flow field characteristics of the actuator under different excitation frequencies were studied by electrical parameter measurement and high-speed schlieren observation. The experimental results indicated that the time required to establish a complete discharge channel of ME-PSJA was less than 2 μs. The real-time response frequency was greater than 1 400 Hz. When the frequency was lower than the saturation frequency, increasing the frequency can effectively improve the time average momentum and diffusion range of the synthetic jet, and enhance the flow control ability of ME-PSJA. However, When the frequency surpassed the saturation frequency, ME-PSJA cannot continuously generate stable jet, leading to a reduction in operation reliability.
