Development of Two-Dimensional Numerical Wave Flume for Wave Interaction with Rubble Mound Breakwaters

Abstract

The numerical wave flume VOFbreak2 for simulation of wave interaction with a rubble mound breakwater is presented. The key innovations are a porous flow model and wave boundary conditions. The porous flow is implemented using a Forchheimer model. At the boundaries waves are generated using a combined wave generation-absorption technique and are absorped using a numerical sponge layer.
