Numerical simulations of super rogue waves in a numerical wave tank
Ocean Engineering, 2021Abstract Following the experiments of Chabchoub et al. (2012b), super rogue waves up to the fifth order are simulated in a numerical wave tank under the framework of Navier-Stokes equations for the first time. The numerical wave tank solves 2D Navier-Stokes equations by using the Finite Difference Method and simulates free-surface flows by the Volume-

Application of an overset mesh based numerical wave tank for modelling realistic free-surface hydrodynamic problems [PDF]
Ocean Engineering, 2019 This paper presents a numerical wave tank based on the overset mesh approach. Overset mesh is favourable to the moving mesh method owing to its ability to represent complex geometries whilst maintaining a good quality mesh, especially for large amplitude

ON THE SIMULATION OF REGULAR WAVES IN A NUMERICAL WAVE TANK
Advances and Applications in Fluid Mechanics, 2018The use of renewable sources for electricity generation has been accelerated because of high fuel prices of fossil fuels. In addition to this, the use of conventional fuel supplies is no longer able to cater for the ever increasing energy demands of the modern world which is experiencing an age of rapid expansion.

Validation of Wave Propagation in Numerical Wave Tanks
24th International Conference on Offshore Mechanics and Arctic Engineering: Volume 3, 2005During the last few years there has been a strong growth in the availability and capabilities of numerical wave tanks. In order to assess the accuracy of such methods, a validation study was carried out. The study focuses on two types of numerical wave tanks: 1. A numerical wave tank based a non-linear potential flow algorithm. 2. A numerical wave tank

Numerical modelling of wind-modified focused waves in a numerical wave tank
Ocean Engineering, 2018Abstract 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, 2019Abstract 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, 2015Simulation 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
