An aerodynamic inverse design method, which is used in compressors, is introduced in this paper. This inverse design method is based on the exact solution of the local Riemann problem on moving blade surfaces. Furthermore, an improved relaxation factor is added to control the induced velocity for reasonable deformation sizes in different cases. The viscous flow analysis and the inverse design are integrated in the computational fluid dynamics software ANSYS Fluent using the dynamic mesh user-defined function, which reduces the time spent on remeshing the computational domain. A compressor cascade is taken to illustrate the effect of this inverse design method. Using the compressor model, the case of a different loading pattern design under a high subsonic flow regime and the case of a loading smooth design under a transonic flow regime have proved the capability of this inverse design method to realize the prescribed pressure loading distribution.

介绍了一种用于压缩机的空气动力学逆向设计方法。这种逆向设计方法是基于运动叶片表面上局部Riemann问题的精确解。此外，在不同情况下，还添加了改进的松弛因子来控制感应速度，以获得合理的变形大小。使用动态网格用户定义函数将粘性流分析和逆设计集成到计算流体动力学软件ANSYS Fluent中，从而减少了重新划分计算域所需的时间。采取压缩机级联来说明这种逆向设计方法的效果。使用压缩机模型，
