Evaluation of turbulence closure models under spilling and plunging breakers in the surf zone
TL;DR: In this paper, a new library of turbulence models for application to multiphase flows has been developed and is assessed for numerical efficiency and accuracy by comparing against existing laboratory data for surface elevation, velocity and turbulent kinetic energy profiles.
Journal ArticleDOI

TL;DR: In general, the NS solvers appear to predict the behaviour of the structures better than the linearised methods but there is considerable variation in the results (even between similar methods).
Journal ArticleDOI

TL;DR: Results from Blind Test Series 1, part of the Collaborative Computational project in Wave Structure Interaction (CCP-WSI), are presented and there is notable variation in the results, even between similar methods.
Journal ArticleDOI
An evaluation of rans turbulence closure models for spilling breakers
TL;DR: In this paper, open source computational fluid dynamics software is used to evaluate four different turbulence models for the application of spilling breakers in the surf zone, including the nonlinear k-epsilon model.

TL;DR: Results from the CCP-WSI Blind Test Series 2 show heave amplitude is predicted reasonably well by all methods; and a WEC-Sim implementation, with CFD-informed viscous terms, demonstrates comparable predictive capability to even the stronger NS solvers.
