Abstract

Interactions of a shock wave with a gas bubble were visualized by double exposure holographic interferometry or shadowgraph for four combinations of liquid/gas which are silicone-oil (1.0 cSt)/air, silicone-oil (10 cSt)/air, water/air, and water/helium. The gas bubble was exposed to a spherical shock wave generated by detonation of a microexplosive. The gas bubble contracted by hitting of the shock, and a liquid jet formed, as the case may be. Eventually, one or plural rebound shock waves occurred. It was found that there are at least three types of the rebound shock. The generation of it for each type is explained by sequential flow visualizations.
