Abstract

The influence of endwall transverse jet (ETJ) with different slot length and pressure ratio on the secondary flow and loss reduction are numerically investigated. The results show that the skewed jet could suppress the endwall secondary flow and reduce the low energy fluid accumulation in the corner region significantly, thus delaying the boundary separation on the suction side and enhancing the homogeneity of the exit flow angle. The total pressure loss coefficient could be reduced by 11.3% while the jet to inflow mass flow ratio is only 0.3%. With the increase of the slot length and the total pressure of jet, the benefits of ETJ on boundary separation are enhanced, whereas the impact and mixing losses between the jet and the transverse flow are strengthened.
