Simulation of a 3D Numerical Viscous Wave Tank
Journal of Engineering Mechanics, 2007A 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, 2003A 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, 2013A 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.

A Numerical Model for Wave Diffraction in Fully Nonlinear Wave Tank
OCEANS 2006 - Asia Pacific, 2006A numerical model in the time domain is developed for a numerical wave tank (NWT) with the fully nonlinear (or exact) free surface boundary conditions. In this model, an indirect desingularized boundary element method (DBEM) is employed to solve the boundary value problem of velocity potential at each time step and the mixed Eulerian-Lagrangian (MEL ...

Fully nonlinear viscous wave generation in numerical wave tanks
Ocean Engineering, 2013Abstract A numerical method for simulating the complete physics of the fully nonlinear viscous wave generation phenomenon is presented. To accomplish this objective, the motion of a solid body representing the wave generating mechanism is modeled. In this paper, both the piston-type and flap-type wavemakers are simulated and the results of the model ...

Numerical wave tank for the application in ocean engineering
SCIENTIA SINICA Physica, Mechanica & Astronomica, 2011采用FLUENT 软件中的用户自定义函数功能和动网格功能进行造波和消波, 采用VOF 方法捕捉自由液面, 开发了一个数值波浪水池, 该水池可以生成规则波浪、按照波谱生成不规则波浪以及生成既定的不规则波波列. 文中开展了网格和时间步长试验, 力图找到经济精确的网格划分方案和高效的时间步长方案. 文中按照Jonswap 谱进行了不规则波浪的数值模拟, 采用了等分能量法分解波谱的频率区间来得到组成波的 圆频率, 模拟结果显示计算波谱与目标波谱一致, 波浪的统计特征得到了很好的体现, 模拟不规则波波谱的 缺点是耗时过长. 由于真实海况下对海洋浮式结构物造成损坏的往往不是整个波浪时间序列, 而是少数的几个大波或者波列中的波群.
