A Numerical Modeling of Ship Bow Waves

Journal of Ship Research, 1989
A two-dimensional numerical wavemaker model is used to predict the three-dimensional bow wave pattern caused by a wedge-shaped model moving at constant velocity. Solutions with linear and nonlinear free-surface conditions agree well with the experimental result.

Simple analytical relations for ship bow waves

Journal of Fluid Mechanics, 2008
Simple analytical relations for the bow wave generated by a ship in steady motion are given. Specifically, simple expressions that define the height of a ship bow wave, the distance between the ship stem and the crest of the bow wave, the rise of water at the stem, and the bow wave profile, explicitly and without calculations, in terms of the ship ...

Air entrainment by bow waves

1999
Experimental studies of air entrainment by breaking waves are essential for advancing the understanding of these flows and creating valid models. The present study used three-dimensional simulations of a bow wave to examine its air entrainment process.

Bow wave breaking and viscous interaction of stern wave

KSME International Journal, 2000
The bow wave breaking and the viscous interaction of stern wave are studied by simulating the free-surface flows. The Navier-Stokes equation is solved by a finite difference method in which the body-fitted coordinate system, the wall function and the triple-grid system are invoked. After validation, the calculations are extended to turbulent flows. The

High‐frequency electrostatic waves near Earth's bow shock

Journal of Geophysical Research: Space Physics, 1989
Electrostatic wave measurements from the Active Magnetospheric Particle Tracer Explorer Ion Release Module have been used to investigate the wave modes and their possible generation mechanisms in the Earth's bow shock and magnetosheath. It is demonstrated that electrostatic waves are present in the bow shock and magnetosheath with frequencies above the

Electrostatic waves in the bow shock at Uranus

Journal of Geophysical Research: Space Physics, 1989
Electrostatic emissions measured by the Voyager 2 plasma wave detector (PWS) during the inbound crossing of the Uranian bow shock are shown to differ in some aspects from the waves measured during bow shock crossings at Jupiter and Saturn. The wave amplitudes in the foot of the bow shock at Uranus are in general much lower than those detected at the ...

A Bow Wave of Expected Economic Profits

2017
In Chapter 2, we established that the economic return on market value (TSR-Ke) is the fundamental determinant of whether or not wealth has been created for shareholders over a specified measurement period. We also established that (all else being equal), TSR-Ke will be positive if a company takes action that the capital market expects will enable it to

Two-Dimensional Bow Shock Wave Detachment Distances

The Journal of the Royal Aeronautical Society, 1957
In the recent paper by Warren a summary was made of current data on two-dimensional bow shock wave detachment distances. It was shown that the experimental results of Griffith and Alperin, as well as the detachment distances computed by Vincenti and Wagoner, could be collapsed into a single curve by using Spreiter's Transonic Similarity Parameter. This

SPH simulations of bow waves dynamics

2012
The present study aims to provide further understanding of the dynamics of the ship bow waves. From a physical point of view, it is important to understand how the bow wave breaking process develops and how it modifies the wake field. To tackle the problem the ship bow is modeled with simple wedge geometries moving through the water in stationary ...

Whistler waves at the Earth bow shock

2017
The Magnetospheric Multiscale (MMS) spacecraft, with their state-of-the-art plasma and field instruments onboard, allow us to investigate electromagnetic waves at the bow shock and their association with small-scale disturbances in the shocked plasmas. Understanding these waves could improve our knowledge on the heating of electrons and ions across the
