摘　　要：在低速平面叶栅风洞中对光滑叶片及3种非光滑叶片进行了实验研究,分析了非光滑叶片对叶栅出口流动特性的影响. 实验结果表明,采用非光滑叶片改变了叶栅出口旋涡结构及流动分布,使叶栅出口的流场趋于均匀,叶片可以承受更大的负荷.In the low speed plane cascade wind tunnel, the experiments for the cascades equipped with conventional smooth blades and three non-smooth blades were carried out to study the effects of non-smooth blades on the cascade exit flow characters. The experiment results show that using non-smooth blades can change the exit streamwise vortex structures. The exit flow fields tend to well-distributed. The overall blade losses are reduced.
