Abstract
This paper reports the results of experimental results of shock wave/ bubble interaction in a highly viscous liquid. In the medical applications of the shock waves, it is necessary to consider the viscous effect of water. The magma fragmentation is considered to be one of the major mechanisms of the explosive-type volcano eruptions. The dynamic motion of magma should be experimentally investigated from the view point of shock wave dynamics. Silver azide pellet was exploded in silicone oil and starch syrup with various viscosity was visualized by shadowgraph using high speed video camera.
