Water entry of projectiles, 2014

Abstract: The free-surface impact of solid objects has been investigated for well over a century. This canonical problem is influenced by many physical parameters, including projectile geometry, material properties, fluid properties, and impact parameters. Through advances in high-speed imaging and visualization techniques, discoveries about the underlying physics have improved our understanding of [...]

Cavitation of a submerged jet, 2013

Abstract: A cavitation cloud forms when a high-pressure water jet is submerged in a tank of quiescent water. The water jet is formed as high-pressure nitrogen forces a fixed-volume column of water through a nozzle. The diameter and exit velocity of the water jet affect the behavior and geometry of the resulting [...]

Determining 3D flow fields via multi-camera light field imaging, 2013

Abstract: In the field of fluid mechanics, the resolution of computational schemes has outpaced experimental methods and widened the gap between predicted and observed phenomena in fluid flows. Thus, a need exists for an accessible method capable of resolving three-dimensional (3D) data sets for a range of problems. We present a novel [...]

Physics of elastic spheres skipping on water, 2013

Abstract: It is well known that one can skip a stone across the wa- ter surface, but less well known that a ball can also be skipped on water. The Waboba?R is an elastic ball used in a game of aquatic keep away in which players pass the ball by skipping it [...]

Rebound and jet formation of a fluid-filled sphere, 2012

Abstract: This study investigates the impact dynamics of hollow elastic spheres partially filled with fluid. Unlike an empty sphere, the internal fluid mitigates some of the rebound through an impulse driven exchange of energy wherein the fluid forms a jet inside the sphere. Surprisingly, this occurs on the second rebound or when [...]

Unsteady forces on spheres during free-surface water entry, 2012

Abstract We present a study of the forces during free-surface water entry of spheres of varying masses, diameters, and surface treatments. Previous studies have shown that the formation of a subsurface air cavity by a falling sphere is conditional upon impact speed and surface treatment. This study focuses on the forces experienced [...]

Three-dimensional bubble field resolution using synthetic aperture imaging: application to a plunging jet, 2012

Abstract: A methodology for resolving three-dimensional (3D) bubble fields using 3D synthetic aperture imaging (SA imaging) is developed and applied to the bubbly flows induced by a turbulent circular plunging jet. 3D SA imaging involves capturing entirely in-focus images in an array of cameras with multiple viewpoints, then reprojecting the images into [...]

Water entry of spinning hydrophobic and hydrophilic spheres, 2011

Abstract: An experimental investigation of the trajectories, forces and cavity formation behind spinning hydrophobic and hydrophilic spheres is presented. Several cases are also presented for non-spinning spheres which are half hydrophobic and half hydrophilic. Data from high speed imaging are processed using advanced data techniques to gain accurate position, velocity and acceleration [...]
