Numerical Simulations of the Shockwave Induced Collapse of Bubbles Near Surfaces


In the study of collapsing bubbles and their relation to surface erosion, two mechanisms are identified as of major significance: the high-speed liquid jet and the water-hammer shock wave that is subsequently formed. In the current work, we suggest that secondary mechanisms such as the emission of shockwaves following the collapse of the bubble remains and the late-time wave interactions may also be of importance when it comes to surface erosion. We examine our hypothesis by considering the collapse of a bubble by a shock wave that runs in a direction that is parallel to a solid surface.
