Abstract

 In this study, the Faraday wave field, created in vertically oscillating cylindrical containers, was investigated to experimentally simulates a flip-through event caused by concentric focusing waves. We found parametric free-surface oscillation featuring transient oscillation modes. When a cavity, formed at a center of the container, is collapsed by convergent concentric waves, the cavity surface is ejected at high vertical acceleration to form the vertical flip-through jet. Capillary waves, generated at the tip of jet, propagate with orientation of the Faraday oscillation mode, which contributes breakup of the flip-through jet.
