COMPARISONS OF NUMERICAL RANDOM WAVE SIMULATORS

Numerical Simulation of Random Irregular Waves for Wave Generation in Laboratory Flumes

Understanding of wave hydrodynamics and its effects are important for engineers and scientists. Important insights may be gained from laboratory studies.  Often the waves are simulated in laboratory flumes do not have the full characteristics of real sea waves. It is then necessary to present reliable methods of wave generation in wave flumes.  In this paper, the results of numerically simulate...

Numerical comparisons of two long-wave limit models

The Benney-Luke equation (BL) is a model for the evolution of three-dimensional weakly nonlinear, long water waves of small amplitude. In this paper we propose a nearly conservative scheme for the numerical resolution of (BL). Moreover, it is known ([PQ99] and [Pau03]) that (BL) is linked to the Kadomtsev-Petviashvili equation for almost one-dimensional waves propagating in one direction. We st...

Numerical Solution of PDEs on Parallel Computers Utilizing Sequential Simulators

We propose a strategy, based on domain decomposition methods , for parallelizing existing sequential simulators for solving partial diier-ential equations. Using an object-oriented programming framework, high-level parallelizations can be done in an eecient and systematical way. Concrete case studies, including numerical experiments, are provided to further illustrate this parallelization strat...

Numerical Simulation of Wave Overtopping Over Composite Berm Breakwater

Breakwaters have changed a lot during their design history. Overtopping is an important parameter that its evaluation and reduction has always been noticed. In this study, the wave overtopping of composite berm breakwater as a new conceptual structure has been investigated numerical modeling was performed using FLOW-3D software. Then, based on  a laboratory model conducted by Losada et al, cali...
