摘　　要：本文对动静叶相互干扰的非定常流动特性进行了数值研究。研究内容主要涉及两个特定的方面:一方面对叶型优化前后在动静叶干扰的非定常流动条件下的性能进行比较,另一方面对非设计工况有大分离流动的动静叶干扰的特殊性进行研究。The unsteady characteristic of rotor/stator interaction was investigat ed by numerical method in this paper. Two special problems were involved. On one hand, the aerodynamic performance before and after blade optimization was compa red under unsteady flow condition of rotor/stator interaction. On the other hand , the specific property of rotor/stator interaction was investigated under off-d esign condition with large separation flow.
