Title:
Large eddy simulation of a collapsing vapor bubble containing non-condensable gas 
Pages contribution:

Abstract:
We investigate numerically the effect of non-condensable gas inside a vapor bubble on the bubble dynamics and the collapse pressure. Free gas in the vapor bubble has a cushioning effect that can weaken the pressure wave and enhance the bubble rebound. In order to access this effect numerically, simulations of collapsing vapor bubbles containing non-condensable gas are performed. In the simulations, the effects of the gas on the rebound and the shockwave energy are monitored for different...    »
