Paper Abstract

The cavitation erosion by laser-induced bubble collapsing near solid boundary is investigated employing a new force sensor together with a hydrophone. The experimental results indicate that liquid-jet formation and acoustic transient emission are both predominant features on the cavitation erosion; both the liquid jet and the acoustic transient play a vital role in the erosion mechanism during the first two stage of bubble collapse. Finally, the erosion mechanism during the first two collapse of the cavitation bubble is summarized and presented.
