本文以压气机叶栅为研究对象,在Re=2.4×105的情况下,开展了端壁射流/抽吸对于压气机叶栅的损失分布与旋涡结构的研究.结果表明,端壁射流与抽吸都能够显著减弱角区分离.位置与角度是射流的关键因素,当射流位置选取在分离线的渐近线时,角区分离能够得到最优的抑制,能够减少总压损失达22.7％.抽吸流动控制中,位置选取是较为关键的因素,但其对位置的敏感性要弱于射流.“,”Endwall jet and suction control have been investigated in a linear compressor cascade has been investigated with Reynolds number of 2.4×105.The distribution of vorticity and vortex structure has been analyzed.The results show that total pressure losses are significantly decreased with jet and suction flow method.Locations and jet flow angle are two key factors for jet flow control.Corner separation losses could remarkably decrease at 22.7％ with the jets and suction position near the asynptotic line of separation lines on suction surface.In suction flow control,location is an significant factor while the losses reduction are not sensitive as in jet flow control.
