High-fidelity simulation of an aerated cavity around a surface-piercing rectangular plate

Abstract

In this work, high-fidelity numerical simulation is employed for the quantitative study of an aerated cavity induced by a surface-piercing plate. Numerical simulation shows that a large-scale aerated pocket with a conical shape is formed at the fringe of the plate, many bubbles pinching off from it. Numerical results reveal that in the process of free-surface flow around a semi-submerged structure, the aerated cavity contributes a majority of air entrainment in the wake.
