Numerical Analysis of the Internal Kinematics and Dynamics of Three-dimensional Breaking Waves on Slopes

摘要

In this paper, we describe the breaking and post-breaking in a three-dimensional numerical wave tank of a solitary wave over a sloping ridge. The numerical model is based on coupling a higher-order Boundary Element Method (BEM) solution of fully nonlinear potential flow equations to a Volume Of Fluid (VOF) method solving Navier-Stokes or Euler equations, in three-dimensions (3D). The BEM solution is used as an initialization of the VOF/Navier-Stokes solver. Analysis of wave profiles and kinematics (velocity, vorticity, pressure) are carried out.
