Effects of atmospheric pressure on water entry of hydrophobic spheres
Abstract eng: We report an experimental study of water entry of a hydrophobic sphere, which is initially released by an electromagnet and freely falls downward in a sealed equipment. The sphere firstly impacts the water surface and generate a splash, then a cavity is developed when the sphere moves inside the water, and finally a jet is formed after the cavity pinch-off. Here, the effects of atmospheric pressure on such water entry phenomena are presented. Our work especially demonstrates its influence on the splash shape, the surface seal and cavity moving velocity.
