Description
Summary:Abstract Breaking wave effect on Wave Energy Converter (WEC) represents an important issue of site selection analysis especially fringing reefs area. To learn a more acceptable sense of the influence of this effect, an introspection on the estimate of initial breaker points is proposed in the present study. The paper describes an investigation of the impact assessment of wave-breaking criteria subjected to WEC recently desired as a benchmark by the previous three wave-breaking methods. The numerical simulation is carried out by the Computational Fluid Dynamics (CFD) solver. The solver is based on the Finite Volume Method (FVM) to create the discretization of the governing equations. Large Eddy Simulation (LES) is solved in a global approach together with Volume of Fluid (VoF) for capturing free surface. Reported justifications are compared with the experimental data to validate the accuracy of the numerical approach and then applied to generate wave-breaker point location on a fringing reef in Numerical Wave Tank-based (NWT) of 16 scenarios. The results are discussed with respect to relative wave-breaker locations, relative wave-breaker height range, and wave breaking probability under various wave steepness, water depth, and slope fringing reef. It is given regarding the discrepancy between different methods and recommendations for important guidances are outlined.
