    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.
