In this paper the effects of gland leakage on the secondary flow and outlet flow fields in the governing stage stator cascade of a 300mw turbine set are simulated numerically.
The working process model of the rotary vane simulated in the paper takes into account both the leakage and heat transfer model, so it is closer to the practice.
本文建立的旋叶式压缩机工作过程数学模型，综合考虑了泄漏模型与传热模型，更接近实际情况。

One and a half stages of a subsonic compressor were simulated with steady and unsteady calculation, comparing the performance with different combination of tip leakage and seal cavity.
