Abstract The collapses of bubbles near rigid walls are seen widely in engineering and medical applications, examples are surface cleaning, sonoporation, under water explosion, and cavitation erosions, to name a few. Recent experimental studies demonstrated that only bubbles with extremely small stand-off distance γ (γ = d/Rmax, γ is stand-off distance, d is the initial distance of the bubble center to the boundary, and Rmax is the maximum radius the bubble would attain) generate severe erosions during the first oscillating circle. This erosion phenomenon, attributed to a self-focusing mechanism, lacks a comprehensive explanation. Here we provided… More >
