摘　　要：为了进一步提高'高压放电'对空气加速的能力,采用粒子图像测速(Particle Image Velocimetry,PIV)技术,研究了电极形状、电极电压、电极间距、布置方式等激励参数对气流的加速度和最终速度的作用规律。研究表明,采用针式电极能获得较高的极间空气诱导速度。研究结果为进一步提高诱导空气速度,掌握高效的流动控制技术奠定了基础。In order to improve the speedup effect of high-voltage discharge acting on the air,the test,in which the PIV(Particle Image Velocimetry) technology was used and carried out to investigate the effect of the key parameter,including the shape,voltage,interval and arrangement of the electrodes.The result showed that the tip electrode can obtain higher induced air speed.In the future,the result can be referred in the research about effective active flow control to get much higher induced air speed.
