摘要
激波和可压缩流向涡相互作用现象近年来成为流体力学研究中的一个热点 .本文在激波风洞中研究了可压缩流向涡与斜激波相互作用的现象 .实验发现 ,相互作用后激波和旋涡均发生不同程度变形 ,但旋涡未发生明显破碎 .并且发现在干扰点附近 ,从涡核发出一束膨胀波 ,这些膨胀波与斜激波作用 。
In this paper,the shock wave/streamwise vortex interaction was investigated experimentally. A shock tunnel experiment was carried out where a streamwise vortex was formed incident upon an oblique shock wave. It was observed that after interaction both the vortex and the shock wave exhibited being deformed to some extent with the vortex still unbroken.It was also found that near the location of interaction,an expansion wave was created from the vortex core,the expansion wave then interacted with the shock wave and nade it bent backwards.
