A BOUNDARY INTEGRAL MODEL FOR SIMULATING SPILLING BREAKERS

Abstract

A boundary integral method is used to simulate spilling breakers. The bottom is also included inthe introduced closed boundary and the problem is directly solved in the physical plane. The method has beenshown to be remarkably stable, and no numerical instability has occurred in any of the calculations. Theresults reveal that both the momentum and total energy are almost constant in time during the simulationperiod. As a result, the breaking process of a spilling breaker is fairly well simulated.
