摘要

在压气机叶栅叶片两侧布置电极

对电极施加高压高频交流电产生等离子体

通过三孔探针测量栅后总压和速度的变化.实验中发现

流速低于20 m/s时

加电产生等离子体后

可显著改善栅后总压和速度分布;流速接近0 m/s时

等离子体仍会明显改变总压和速度的最小值;出现流动分离趋势后

等离子体无法抑制分离趋势;对分离区大小、分离涡强度的影响还需进一步的实验研究.

Abstract

A pair of electrodes attached to the surface of compressor blade were supplied with high voltage and high frequency alternate current and as a result plasma is produced near the electrodes.Tri-hole tube was used to measure total pressure and velocity in the wake.When the incoming velocity was low

total pressure and velocity in the wake were increased greatly by plasma.As velocity increased

the effect of plasma weakened.The effect of plasma could still be observed as velocity increased to 50 m/s.Plasma is not effective in diminishing the trend of flow separation when it occurs.As to the size of separation zone and intensity of separation vortex

further study is needed.
