The numerical simulation verified by an experiment was conducted to study mechanism of loss generation of the compressor cascade with tip clearance which bowed angle is 60°.The effect of endwall boundary layer aspiration on flow property was studied by means of boundary aspiration on endwall. Results show that flow in tip and corner assumes three dimensional property, and via boundary aspiration on endwall, the tip leakage vortex generation was delayed, and the phenomenon of vortex breakdown was eliminated, so that the flow performance was improved.
