Abstract: We present the results of a combined experimental and theoretical investigation of the vertical impact of low-density spheres on a watersurface. Particular attention is given to characterizing the sphere dynamics and the influence of its deceleration on the shape of the resulting air cavity. A theoretical model is developed which yields [...]
A spin on cavity formation during water entry of hydrophobic and hydrophilic spheres, 2009
2009, Cavitation
Abstract: Surface coating and impact velocity can dramatically affect cavity formation during water entry of spheres. Duez et al. [Nat. Phys.3, 180 (2007)] present a theoretical limit, dependent on impact velocity and surfacestaticwetting angle, below which air cavities no longer form. We show that transverse spin alters the spheres surface velocity distribution to straddle [...]
