| 摘 要： | 通过等离子体激励控制圆柱绕流的实验,研究了等离子体电源激励电压和等离子激励器激励电极数目对圆柱绕流流动控制效果的影响。研究表明,较高的激励电压可以获得较强的流动扰动,达到较好的流动控制效果;较多的激励电极数目可以激励较大区域的边界层流动,有利于增强流动控制效果。

| Abstract: | Experiments are performed to investigate the effect of plasma power supply voltage and the numbers of plasma actuator electrodes on the flow control effectiveness of the test cylinder.It is demonstrated that with a higher actuating voltage,an enhanced flow disturbance could be attained,and a better flow control effectiveness is achieved.It is also observed that when more electrodes are activated,larger area of boundary layer would be activated,which is beneficial to enhancing the flow control effectiveness. |

| Keywords: | plasma flow control the cylinder-around-flow electrode |
