Abstract

In order to reveal the influence of different tip geometries on the leakage flow of the compressor cascade gap, the numerical simulation was carried out to study the variation of the leakage vortex with six different tip geometries in a compressor cascade. Results show that the reasonable tip geometry can reduce the loss of the tip of a certain extent, and different geometric schemes of tip have good effect on improving the air flow deflection and flow capacity of cascade. The suction surface of the blade tip cutting is the most effective method to control the loss and improve the performance of the cascade.

Key words： leakage flow; leakage vortex; tip geometry; total pressure loss
