Vorticity Instabilitties in Wave-Breaking Process: Formations of 3D Vortex Structure, Finger Jets and Sea Sprays

Abstract

This paper presents vorticity instabilities occurring during wave breaking process, which interprets formations of the initial three-dimensional vortex structure, scarifying and fingering surface via surface-vorticity interactions, and the sea-spray fragmenting from the finger jets. Three-dimensional linear instability analyses are performed for identifying these instability modes to describe a series of local surface deformations featuring the splashing process in this study.
