A 3D Numerical Wave Tank for Coastal Engineering Studies

Defect and Diffusion Forum, 2017
This paper presents the validation of active and passive, made by a dissipation beach, numerical absorbing methods implemented in RANS-VOF FLUENT® code for modelling long time series of wave propagation interacting with coastal structures. Verification of both numerical techniques was performed in 2D – wave flume, and 3D – wave tank, this one using a ...

Comparison of Numerical Methods for Wave Generation by VOF-Based Numerical Wave Tank

Volume 6: Ocean Engineering, 2011
Based on the Reyonlds Averaged Navier-Stokes (RANS) equation for incompressible, viscous fluid, a VOF-based numerical wave tank which could accurately generate and absorb waves is investigated. Three different wave-making functions, namely ‘Inlet-velocity boundary condition (IBC)’, ‘Momentum source (MOS)’, ‘Mass source (MAS)’ are investigated, and the ...

Numerical wave tank based on a conserved wave-absorbing method

China Ocean Engineering, 2015
Recently the numerical wave tank has become a widely-used tool to study waves as well as wave-structure interactions, and the wave-absorbing method is very important as its effect on the quality of waves generated. The relaxation method and the derived momentum source method are often utilized, however, the damping weight is constant during calculation

Numerical wave tank modelling of regular waves propagation using OpenFOAM

2017 3rd International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET), 2017
The physical testing of coastal wave/structure interaction is conventionally performed in a wave basin. However, the investigation requires specialized facilities and manufacturing of scaled models which are costly in both time and money. This paper outlines the development of Numerical Wave Tank (NWT) for the Universiti Teknologi PETRONAS (UTP) wave ...

Numerical Modeling of Wave Absorbers for Physical Wave Tanks

Journal of Waterway, Port, Coastal, and Ocean Engineering, 2003
A 3D numerical solution was derived to determine the wave field in a physical wave tank equipped with a porous wave absorber of variable width and draft. The solution was achieved by applying the boundary element method. The model was applied to analyze the effect of the geometry and material of wave absorbers on wave reflection to eventually equip a ...

A Nonlinear Numerical Wave Tank and its Applications

Volume 9: Odd M. Faltinsen Honoring Symposium on Marine Hydrodynamics, 2013
A two-dimensional fully nonlinear numerical wave tank is developed by using a boundary element method (BEM). The water depth can be shallow or deep. The waves are generated by simulating a piston wave maker or by specifying the input velocity at the upstream boundary.

Simulation of a 3D Numerical Viscous Wave Tank

Journal of Engineering Mechanics, 2007
A numerical scheme was developed to solve the unsteady three-dimensional (3D) Navier–Stokes equations and the fully nonlinear free surface boundary conditions for simulating a 3D numerical viscous wave tank. The finite-analytic method was used to discretize the partial differential equations, and the marker-and-cell method was extended to treat the 3D ...

Numerical Simulation of Nonlinear Waves in Numerical Wave Tank Using Boundary Element Method

2015
Increasing world population and consequent increase in fossil fuel consumption emerge the necessity of looking for new sources of energy, resources that are clean, cheap, and renewable. The extracted energy from the sea is one of the alternatives of fossil fuels. This energy is available either in the form of tidal or wave energy.
