Water-entry for a wedge in arbitrary water depth
Engineering Analysis with Boundary Elements, 1994Abstract Numerical and experimental results are presented for the two-dimensional entry of a wedge into initially calm water of arbitrary depth. In the numerical computation, the flow field is solved by the boundary element method with nonlinear free surface boundary conditions.

From water entry to lock entry
Journal of Hydrodynamics, 2010In this paper, the ship lock entry problem is studied, which is physically similar to, but numerically different from, the water entry problem simulated by the author 25 years ago under the instruction of Prof. He. A one-dimensional unsteady hydraulic narrow-channel model for the flow coupled to the ship’s motion in surge, heave and pitch is formulated

Entry of Water into Silica Glass
Nature, 1958SOME specimens of silica glass absorb infra-red radiation of wave-length near 2.7µ. Garino-Canina1 observed that the occurrence or absence of the band in his specimens depended on whether or not water vapour was present when the glass was made (by fusing quartz crystal). Following Harrison2, he attributed the absorption to hydroxyl groups bound to some

The movement of water around the hydrological cycle takes place in response to a series of merging potential gradients, the water moving because there is nothing to stop it; obviously at some point in the cycle a substantial quantity of energy must be injected and as we have seen this comes from the sun and is used almost entirely in the conversion of ...

A STUDY OF THE WATER-ENTRY CAVITY
1963Abstract : For missiles producing clean cavities after water entry the cavity development is shown by theory to depend significantly only on: entry angle, an effective mass, and a Froude number based on the nose-flat diameter. A method is outlined for estimating pressures in closed, almost-steady cavities, from cavity geometry. Data from application of

Vertical Entry of Missiles into Water
Journal of Applied Physics, 1952Investigations, carried out principally on the vertical water entry of steel spheres, are described. Graphs show the effect of several experimental parameters on the time and place of occurrence of various events in the life of the cavity which accompanies the entry.

Vertical entry of solids into water
Fluid Dynamics, 1985The vertical inertial entry of spheres and disks of various masses into water has been investigated experimentally. The values of the virtual mass and the drag coefficients are estimated with the aid of high-speed photography of the penetration process. An expression is obtained for the nonstationary cavity near the body.

Violent water entry of spheres
European Journal of Mechanics - B/Fluids, 2019Abstract Water entry is an impulsive two-phase flow often met in nature and in industrial processes. Violent vertical entries are observed when the projectile is heavy and when the Froude number is high enough: they form a distinct category characterized by an elongated cavity trailed by the projectile.
