Efficient Nonlinear Hydrodynamic Models for Wave Energy Converter Design—A Scoping Study
Josh Davidson,Ronan Costello +1 more
TL;DR: In this article, the authors focus on the most suitable form of hydrodynamic modeling for the next generation wave energy converter (WEC) design tools, focusing on what CFD theories exist intermediate to LPF and RANS as well as other modeling options that are computationally fast while retaining higher fidelity than LPF.

Development and validation of a non-linear spectral model for water waves over variable depth
TL;DR: In this paper, two numerical schemes for propagating waves over a variable bathymetry in an existing High-Order Spectral (HOS) model are introduced, and the numerical properties (accuracy, convergence rate, efficiency) with respect to the numerical parameters on a simple configuration are investigated.

A comparative study of two fast nonlinear free-surface water wave models
Guillaume Ducrozet,Harry B. Bingham,Allan Peter Engsig-Karup,Félicien Bonnefoy,Pierre Ferrant +4 more
TL;DR: In this article, a comparison between two fully nonlinear potential flow solvers for the solution of gravity wave propagation is presented. And the results show that the HOS model is more efficient than OceanWave3D with a difference dependent on the level of accuracy needed as well as the wave steepness.
