In order to investigate the effects of the tip injection location on tip leakage flow of turbine,the detailed flow-field measurements at cascade outlet are taken with a five-hole probe for the turbine cascade with various tip-injection locations and tip clearance sizes under low speed conditions. The 3D flow fields near the tip region are compared by CFD simulation,and the effects of the tip injection location on the flow fields and losses are analyzed. The results show that the impacts of the blade tip inj...
