| 摘 要： | 本文从涡动力学原理出发，根据实验测量和流场显示结果，对压气机平面叶机的壁面拓扑和叶栅二次流结构进行了研究．由叶栅壁面拓扑分析和二次流结构可知，叶栅的通道涡较强，出口集中脱落涡和角区分离泡的存在，造成了叶栅两端区较高的二次流损失，并且随叶栅来流冲角的提高，旋涡出现破裂，二次流损失进一步提高．

| Abstract: | Based on the principle of vortex dynamics, the topological and secondary flow structurein compressor cascade are studied in this paper. viom the experimental investigation andflow visualization it is shown that the passage vortices are quite strong in the cascade anddue to the existence of the concertreted shed vortices and corner vortices, the secondary lossat the two ends is much high. When the incidence increases, the vortices in the cascademight separate and break down and the secondary loss increases still further. |
