Abstract
In this paper, an explosion, which starts at the center of a vortex, is considered. A shock tube was used to conduct the experiment. A vortex is generated when the shock wave propagates around a wing-shaped model. The explosion is triggered at the time when the vortex arrives at the position where the explosion wire is located. Holographic interferometery was used to visualize the vortex-explosion interaction. Both experimental and numerical results showed that a vortex, after disturbed by an explosion, is strongly deformed and smeared out, which suggets that vortex might be suppressed or even destroyed with an explosion. More careful works need to be carried out in the near future in order to get more detailed and quantitative information for both academic and application interests.
