Water entry of spinning spheres
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 anticipated, the spinning motion induces a lift fo...

متن کاملWater entry of small hydrophobic spheres
We present the results of a combined experimental and theoretical investigation of the normal impact of hydrophobic spheres on a water surface. Particular attention is given to characterizing the shape of the resulting air cavity in the low Bond number limit, where cavity collapse is driven principally by surface tension rather than gravity. A parameter study reveals the dependence of the cavit...
متن کاملThe Effect of Asymmetric Water Entry on the Hydrodynamic Impact
The effect of the asymmetric water entry over a submerged part of a ship on the hydrodynamic impact is investigated numerically. A wedge body is considered to study and the problem is assumed to be two-dimensional. The Results of symmetric and asymmetric impacts are compared together. The effect is found significant in the numerical simulation. The maximum hydrodynamic pressure at a heel angle ...
متن کاملAcoustics of water saturated packed glass spheres
2014 We have measured the velocity and attenuation of sound in a pack of water saturated glass spheres. The frequency range spreads from 200 kHz to 10 MHz and the diameter of the spheres is varied from 50 03BCm to 500 03BCm. Our experimental data clearly confirm the validity of Biot’s theory of the propagation of sound in porous medium. J. Physique LETTRES 42 (1981) L-477-L-480 Classification P...
