通过跨音速透平平面叶栅气动试验所拍摄的纹影照片,分析讨论了在叶栅槽道及出口流场里的激波形成与发展。根据试验结果,论证了在自由边界面上反射激波的存在及其对流动特性的影响。在本文的第三部分对激波与附面层干扰的几种典型现象进行了讨论。
The formation and development of shock waves in the cascade channel and exit flow field are analyzed and discussed through the smear pictures taken by the transonic turbo plane cascade aerodynamic test. According to the experimental results, the existence of reflected shock on the free boundary surface and its influence on the flow characteristics are demonstrated. In the third part of this paper, several typical phenomena of shock and surface interference are discussed.
