摘要：By using of CFD numerical simulation, boundary layer suction on endwall of a transonic compressor stator at near stall condition was researched.Three schemes of boundary layer suction at the endwall of compressor stator were discussed.There are end wall leading edge suction, the near the trailing edge suction and combination suction.The results show that the boundary layer of the leading edge suction on stator endwall will be depressed, the flow separation at the corner will be restrained, the flow loss will be decreased, and the stall margin will be increased.The low energy fluid in the separation region will be sucked out in the scheme of the suction near the trailing edge, the effect is not obvious.The effect of the combination suction scheme will be between the former two.
