摘要:
Based on boundary integral method a numerical investigation of two cavitation bubbles collapsing axisymmetrically near a rigid wall shows that when the Weber number is less than or equal to 20 the surface tension has obvious effects on their collapsing behaviors, which makes the period of the collapse apparently shorter and the jet wider and shorter. When the action of the upper bubble and the wall to the lower bubble is very close the surface tension has substantial effects so that the collapsing pattern is qualitatively changed.
