Experiment of flow separation control in highly loaded compressor cascade corner by endwall plasma aerodynamic actuation

  • 摘要: 为揭示端壁等离子体气动激励抑制高负荷压气机叶栅角区流动分离的影响规律和流场特征,在不同流场参数和激励条件下分别开展了微秒脉冲和纳秒脉冲等离子体气动激励抑制叶栅流动分离的实验研究.结果表明:端壁等离子体气动激励可以有效抑制叶栅角区的流动分离,其作用效果在攻角为3°时最佳,随攻角的增大逐渐下降;微秒脉冲激励的流动控制效果随来流速度的增大而降低,随激励电压和占空比的增大而提高,最佳非定常脉冲频率为500Hz;在较高来流速度下,微秒脉冲激励的作用效果十分微弱,但纳秒脉冲激励能够有效抑制角区流动分离;纳秒脉冲激励的流动控制效果随激励电压增大而提高,激励频率对控制效果至关重要,作用效果随激励频率的增大而不断增强,但当激励频率为5kHz时,作用效果有所下降.
