Cavity and projectile dynamics in intermediate Froude number water entry

Abstract

Introduction: Water entry of projectiles has long been a topics of interest in both sciences and engineering. It began with Worthington, who in the late XIX century found experimentally that a cavity is being formed when a steel sphere enters water (Worthington and Cole (1895-1896)). As we know today, water entry of a sphere is a complex process which nonetheless can be enormously simplified, making it a particularly rewarding area of research.
