Wave Energy Dissipation Using Perforated and Non Perforated Piles
The indispensable vital structure in any harbor is a breakwater in order to make available calm water region inshore. Pile breakwater can be employed as a small coastal protection structure where tranquility required is low. This study is concerned with CFD study on the performance of perforated hollow pile to dissipate wave energy and the novelty of this investigation is the role of perforatio...
متن کاملDam Break Wave with Energy Dissipation : Two Case Studies
Abstract: Flood waves resulting from dam break and spillway gate malfunction may have dramatic impacts. Two related cases are the overtopping of a dam by flood waves and a sudden water release down a stepped cascade. In each instance, some energy dissipation takes place and classical dam break theory are inappropriate. Both cases were investigated in large-size facilities and in a prototype. Ne...
متن کاملSpectral Cascade and Energy Dissipation in Kinetic Alfvén Wave Turbulence
Spectral cascade and energy dissipation of Alfven turbulence is studied using a massively parallel gyrokinetic particle simulation. The simulation observes a magnetic energy spectrum with a power law index of ”-5/3” in the long wavelength, which agrees with magnetohydrodynamic results in the inertial range. In the dissipation range, the simulation finds a spectral break point on the ion gyrorad...
متن کاملWave Propagation at the Boundary Surface of Elastic Layer Overlaying a Thermoelastic Without Energy Dissipation Half-space
The present investigation is to study the surface wave propagation at imperfect boundary between an isotropic thermoelastic without energy dissipation half-space and an isotropic elastic layer of finite thickness. The penetration depth of longitudinal, transverse, and thermal waves has been obtained. The secular equation for surface waves in compact form is derived after developing the mathemat...
متن کاملDark energy and dissipation
Most of the models leading to a current state of cosmic accelerated expansion fail to address the coincidence problem, i.e., that the dark energy density and the energy density of the matter fluid are of the same order precisely today. We show that a way to drive late acceleration and simultaneously solve the aforesaid problem is assuming the matter fluid dissipative [1]. 1 General setting The ...
