摘要
本文介绍了平面运动激波和单个旋涡二维相互作用的实验。实验在方截面激波管中进行,实验中拍摄了激波和旋涡相互作用全过程的纹影照片。实验结果发现,运动激波通过涡核时发生激烈变形并在波后流场中产生圆柱形声波。
This paper presents an experiment on two-dimensional interaction of a plane moving shock with a vortex.The experimentswere conducted in a shock tube with square cross section.A series ofschlieren photographs of shock-vortex interaction were taken in theexperiments.The results show that the shock surface is disturbed anda cylindrical sonic wave occurs during the shock wave passes throughthe vortex core.
