在方截面激波管中进行了平面运动激波和涡对的二维相互作用实验,研究了激波与同向涡对、激波与反向涡对相互作用的非定常过程.根据实验照片,分析讨论了作用过程中激波的变形,二次激波和三波点的形成、演变,激波与激波的相互作用,以及旋涡结构的变化等.实验表明,激波通过涡核时,激波发生剧烈变形,旋涡强度增大,涡核形状改变.
The two-dimensional interaction of plane-motion shock wave and vortex pair in a square-section shock tube was studied. The unsteady process of interaction between shock wave and co-vortex pair and shock wave and reverse vortex pair was studied. According to the experimental photograph, the deformation of the shock wave, the formation and evolution of the second shock wave and the third wave point, the interaction between the shock wave and the shock wave, and the changes of the vortex structure are analyzed and discussed. Experiments show that when the shock wave passes through the vortex core, the shock wave undergoes severe deformation, the vortex intensity increases, and the shape of the vortex core changes.
