One and a half stages of a subsoniccompressor were simulated with steady and unsteady calculation, comparing the performance with different combination of tip leakage and seal cavity.
The accuracy and realability of the numerical software used to simulate the flow field of subsoniccompressor is verified by the experiment data of a certain low speed two stage repeated compressor.
采用低速重复级压气机实验数据，验证了本文所采用的数值方法模拟亚声速压气机流场的精度和可靠性。
