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-

Numerical simulation of regular waves: Optimization of a numerical wave tank
Ocean Engineering, 2018Abstract With the growth registered in computational power, numerical models applied to fluid flows is an increasingly important tool for oceanic and coastal engineering, and can be used in studies including energy converters. The main objective of this work consists of using a Computational Fluid Dynamics (CFD) software, ANSYS® CFX®, to study the ...

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

Studies on the performance of Savonius rotors in a numerical wave tank
Ocean Engineering, 2018Waves were generated in a numerical wave tank (NWT) using a piston type wave-maker. Firstly, the performance of a 1.8 m diameter Savonius rotor was tested at a mean wave height (H) and a mean wave period (T) of 2.00 m and 12.68 s respectively.

A 3D Numerical Wave Tank for Coastal Engineering Studies
Defect and Diffusion Forum, 2017This 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 ...
