Abstract

Shock wave propagation and collapse of gas bubbles caused by a shock in a water containing gas bubbles are of large interest in relation to characteristics of water hammer, blowdown of high pressure liquids in pipes, damping of dynamic influence of shock waves on obstacles, etc. The large-amplitude shock wave propagations in the bubbly liquid are investigated using a two-phase shock tube. Effects of incident shock wave strength and initial void fraction on shock wave pressure characteristics are clarified for incident shock wave strength ranging from 0.06 MPa to 0.25 MPa. Behavior of the bubbles collapsing behind large-amplitude shock waves is also clarified by pressure history measurements and high speed photography.
