摘要
以某型航空发动机的压气机平面叶栅为研究对象,基于Gambit软件建立叶栅模型并划分网格,采用Fluent软件,仿真计算了不同攻角时叶栅通道内流场的流动情况,比较分析了不同攻角时叶栅通道的流动特性。仿真结果对压气机的设计和改进具有一定的指导意义。
Aiming at the aero- engine compressor,it establishes a 2- D cascade model and meshes with the software of Gambit,analyzes the flow field of different attack angle based on software of Fluent. It compares the characteristics of different attack angle. The results can be used to guide the design and improvement of the compressor.
