A wave energy equation is developed to evaluate the energy of waves propagating over an irregular bottom. The model equation includes energy dissipation caused both by wave breaking and bottom friction. Coefficients appearing in the model equation are evaluated based on laboratory experiments expressly ...
Wave energy fluxes calculated by integration over all frequency and direction bins of the random waves, which can be regarded as the most accurate equation, are used for validating the two equations. It is demonstrated that the GWEAE significantly improve the accuracy of the wave energy estimation...
This study extends an energy-balance-equation wave model (a phase-averaging wave model) for multidirectional random wave transformations to account for wave shoaling, refraction, diffraction, reflection and breaking. Quadratic upstream interpolation for convective kinematics is used in the discretization to...
Winterbone FREng, BA, BSc, PhD, DSc, Ali Turan, in Advanced Thermodynamics for Engineers (Second Edition), 2015 1.5.8.2 Steady flow energy equation The steady flow energy equation is a particular case of the USFEE, and may be derived from Eqn (1.30) by making the following assumptions: ...
We consider the wave equation with a damping term on a partially rectangular planar domain, assuming that the damping is concentrated close to the non-rectangular part of the domain. Polynomial decay estimates for the energy of the solution are established.关键词: Energy decay for damped wave eq...
An energy conservative scheme is proposed for the regularized long wave (RLW) equation. The integral method with variational limit is used to discretize the spatial derivative and the finite difference method is used to discretize the time derivative. The energy conservation of the scheme and existe...
Ponderomotive force expressions are obtained and the perturbation in the total energy–momentum tensor due to a one-dimensional wavepacket is found. A nonlinear Schrdinger equation is obtained for the evolution of a three-dimensional wavepacket. Both hot and cold plasmas are treated. 展开 ...
Quantization of wave energy is a phenomena that naturally arises due to the properties of waves, and the exact origins of quantization can be found by studying the Schrodinger equation.What is Quantization of Energy? In classical mechanics, an object has a continuous total energy. For example, ...
According to the Newton’s second law, a following equation is derived:Fa−msbg−mbg=0where: Fa is the Archimedes force, msb is mass of the sub-buoy, mb is mass of the ballast. The Archimedes force can be computed as follow:Fa=π3ρg(2a3−3a2z+z3)where: z is the distance ...
