In order to improve the aerodynamic performance of the rectangular expansion pressure cascade, this paper studies the influence of different widths of small wings on the aerodynamic performance of the rectangular expansion pressure cascade.In the study, we used numerical simulation method to model and simulate the rectangular expansion pressure cascade. By analyzing the flow field and pressure distribution of rectangular expansion pressure cascade with different widths of small wings, we obtained the influence of different small wing widths on the aerodynamic performance of the rectangular expansion pressure cascade, as well as the performance under different operating conditions.精品文档---下载后可任意编辑The results show that the aerodynamic performance of rectangular expansion pressure cascade will be significantly improved with the increase of small wing width. At the same time, under different operating conditions, the performance of rectangular expansion pressure cascade with different small wing widths is also different. Therefore, in the actual application of rectangular expansion pressure cascade, suitable small wing widths should be selected according to the specific operating conditions to improve the aerodynamic performance of the cascade.【Key words】Rectangular expansion pressure cascade; Small wing; Aerodynamic performance; Numerical simulation
