Numerical modelling of wind-modified focused waves in a numerical wave tank

Ocean Engineering, 2018
Abstract In this paper, we extend the non-breaking second-order corrected focused wave experimental results of Sriram et al. (2015) in a numerical wave tank based on HOS in the presence of wind. The wind is modelled using the modified Jeffrey's Sheltering Mechanism (Kharif et al., 2008).

Wave Propagation in CFD-Based Numerical Wave Tank

Volume 1: Offshore Technology; Offshore Geotechnics, 2019
Abstract A heuristic approach to investigate the characteristics of the numerical waves propagating in various CFD-based NWT set ups is proposed to develop an optimal grid system for a numerical wave tank. Linear dispersion relations of the waves in a Cartesian grid system are derived analytically. The analytic results lead to an optimal

Wave simulation in a numerical wave tank, using BEM

AIP Conference Proceedings, 2015
Simulation of linear and non-linear waves in numerical wave tank has been one of the most important topics of interest to researchers and scholars working in the areas of the marine industries. In this paper, due to capabilities of the boundary element method, nonlinear waves generated by a piston type wave-maker in a 2D wave tank was investigated. For

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 ...

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 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.
