Numerical simulation of cavitation-bubble expansion and collapse inside a bottle subjected to impact on its topside

In this study, we simulate the acceleration-induced cavity bubble expansion and its non-spherical collapse in a drastically varying pressure field caused by mechanical impact, and we qualitatively compare the results with those for similar ζ number (Obreschkow et al., ) as recorded by a high-speed c...
