Numerical investigation of non-condensable gas effect on vapor bubble collapse

We numerically investigate the effect of non-condensable gas inside a vapor bubble on dynamics, collapse pressure and impact spherical aspherical collapses. Free has damping that can weaken wave enhance rebound. To estimate this numerically, we derive validate multi-component model for bubbles containing gas. For cavitating liquid gas, employ homogeneous mixture with coupled equation state all components. The cavitation is barotropic thermodynamic equilibrium model. Compressibility phases considered in order to capture shock collapse. After validating an analytical energy partitioning model, simulations collapsing wall-attached different stand-off distances are performed. rebound emitted well captured.
