Experimental study of the interaction between shock waves and vortex pair
激波与涡对相互作用的实验研究
In the experiment, a simplified aircraft model ( with tail wing) is employed to construct a4-vortex wake system consisting of a pair of tip vortices and a pair of counter rotating tail plane vortices.
试验采用简化的飞机模型(有尾翼),建立了包含一对翼尖涡及一对反向旋转的尾翼涡(通过以负迎角安装尾翼得到)的4涡尾流系统。
The results obtained describe the flow structure in the corner between the end-wall and blade suction surface in detail. Besides a passage vortex with in the passage, there exist a shed corner vortex pair and a secondary vortex pair in the corner.
结果表明:叶栅通道内不仅存在通道涡,而且在吸力面与端壁形成的角区内存在一角区脱落涡对和一二次涡对。
