Abstract

The compressor is developing towards high load and high stability, so in order to reduce the loss of the clearance area under this trend, the winglet could be used in the high subsonic cascade. Numerical simulation was carried out to investigate the effect of different shapes of tip winglets. Results show that an improved aerodynamic performance and a weakened tip leakage is achieved by using different winglets. The improvement effect of the pressure side winglet is more obvious, and the total pressure loss coefficient of PW2.0 is reduced by 4.47% compared with the prototype.
