Abstract
Shock propagation in a stratified liquid layer was investigated experimentally and numerically. A silicone-oil/water combination was investigated. In experiment a spherical shock wave was generated by exploding a 10 mg silverazide micropellet in silicone-oil. Propagation, reflection and refraction of the spherical shock wave over the silicone-oil/water interface was observed by double exposure holographic interferometry. TVD finite difference numerical simulation was also carried out to interpret complicated shock refraction over the two liquid interface. By comparison between the experiment and numerical solution, discussion was made in some detail.
