摘　　要：本文对非设计工况下动静叶栅相互干扰的非定常流动特性进行数值研究。非设计工况主要考虑大攻角下的分离 流动,动静叶干扰的非定常流动的数值求解在N—S方程的基础上采用分区计算的方法来完成。数值分析结果揭示了在分 离流动本身的非定常特性与动静叶栅相互干扰的非定常特性的双重影响下的流场情况。The unsteady characteristic of rotor/stator interaction under off-design condition was investigated by numerical method in this paper. The off-design condition has the separation flow caused by large attack angle. Based on Navier-Stokes equations, the numerical solution of unsteady flow of rotor/stator interaction was completed with the method of inviding into multiple computational regions. The computed results show the flow field characteristic under the influence of both separation flow and rotor/stator interaction.
