Jetting mechanisms in bubble-pair interactions

Jetting mechanisms in cavitation bubbles play a crucial role the destructive forces of cavitation. Depending on application, these can have desirable effects like medical treatments or catastrophic erosion ship propellers. Still today, thorough understanding all details complex bubble collapse scenarios is lacking. Hence, this work, we numerically investigate jetting for air pairs water following recent experimental setup. We apply finite-volume approach with fifth-order low-dissipation shock-capturing weighted essentially non-oscillatory reconstruction. The interface interaction described by conservative sharp-interface level-set method. For time integration, third-order total-variation-diminishing Runge–Kutta scheme employed. Complementing observations, our simulations reveal presence dominating gas jets and new types mechanisms.
