Abstract

An investigation on vortex-explosion interaction was carried out experimentally and numerically. The experiment was conducted in a shock tube, in which a vortex is generated when a shock wave propagates around a wing-shaped model, and an explosion is triggered at the time when the vortex arrives to the position where the exploding wire is located. Holographic interferometry was used to visualize interaction flow field. In the numerical simulation, a series of different conditions in which the explosion is triggered at various positions related to the center of the vortex were considered. Both experimental and numerical results showed that the vortex, after disturbed by the explosion, can be strongly deformed or smeared out, which implies that vortex might be suppressed or even destroyed by the interaction of the explosion, especially when the explosion is started at the center of the vortex.
