Abstract

A 3D numerical model is developed for simulating breaking wave forces acting on a vertical pile. This model is based on the viscous and incompressible Navier-Stokes equations for a two-phase flow (water and air) model and the volume of fluid (VOF) method for the displacement of the free surface. An application based on the Cut-Cell method is employed in order to install complicated obstacles in a computational domain. The free surface elevation, dynamic pressures, and breaking wave forces are calculated by the numerical model, and the computed results show a good agreement with experimental data. The numerical model can be used to estimate breaking wave forces on a vertical pile. Keywords: 3D numerical model, VOF method, Cut-Cell method, breaking wave force, vertical pile.
