Three-dimensional synthetic aperture particle imaging velocimetry, 2010

Abstract: We present a new method for resolving three-dimensional (3D) fluid velocity fields using a technique called synthetic aperture particle image velocimetry (SAPIV). By fusing methods from the imaging community pertaining to light field imaging with concepts that drive experimental fluid mechanics, SAPIV overcomes many of the inherent challenges of 3D particle image velocimetry [...]

The water entry of decelerating spheres, 2010

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

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 [...]

Water-entry of spinning spheres, 2009

Abstract: The complex hydrodynamics of water entry by a spinning sphere are investigated experimentally for low Froude numbers. Standard billiard balls are shot down at the free surface with controlled spin around one horizontal axis. High-speed digital video sequences reveal unique hydrodynamic phenomena which vary with spin rate and impact velocity. As [...]
