Abstract

A numerical analysis model for solving non-linear wave-structure interactions, based on the coupling of a Boundary Element Method (BEM) which is applied to the region far from the structure where the fluid motion is less non-linear and a Volume Of Fluid (VOF) method which is applied to the region around the structure where the fluid motion is highly non-linear, is developed.<BR>Two methods were combined under the principles of continuities of the velocity and the pressure. The validity of the method was checked comparing the numerical results with the experimental ones for surface oscillations around a submerged breakwater. Consequently, combined method can calculate wave field including wave breaking, with the same accuracy of VOF, and with much shorter CPU-time.
