Shock wave propagation and bubble collapse in liquids containing gas bubbles
The large-amplitude shock wave propagation phenomena in air-bubble/ water mixtures were investigated using a two-phase shock tube. Effects of incident shock wave strength and initial void fraction on shock wave pressure characteristics were investigated exp erimentally. The frequency characteristic of large-amplitude shock wave pressure was clarified by the joint time-frequency analysis of shock wave pressure histories. Behavior of the bubbles collapsing behind large-amplitude shock waves was also clarified by pressure history measurements and high speed photography.
