摘要：
This paper investigates the numerical analysis of wave breaking due to a simple model of rectangular shaped floating breakwater to dissipate the incident wave energy and reduce the transmission coefficient. A 2D numerical model is formed to analyze the problem numerically. The volume of fluid (VOF) method is used to calculate the nonlinear phenomena such as the wave profiles and the interaction between waves and the structure. The basic equations used for VOF method are the continuity equation, the Navier-Stokes equation for incompressible fluid and the advection equation that represents the behavior of the free surface. These equations are calculated by a finite difference method using a staggered-mesh. The SOLA scheme is employed to calculate the pressure and flow velocity in each time step. And a type of donor-acceptor flux approximation is used to calculate the advection of the VOF function F performing the free surface. The advections are calculated by velocities of the adjoining cell by using a donor cell which transports a fluid and an acceptor cell which receives a advect fluid.
