Abstract
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 asymptotic 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.
