Cavity dynamics of vertical water entry by air jet
Spheres falling into water create fascinating phenomena, such as crown-like splashes and clear cavities that are subsequently pinched off. These phenomena are universal and are generally controlled by the properties of the sphere. In this study, we report a new cavity formed by an air jet that lacks a distinct splash and features a rough cavity interface. We investigate the cavity dynamics, including formation, development, and pinch-off events.
