Numerical Analysis of Wave Overtopping Failure of Booms with SPH

Booms have been widely used in protecting the coastal area in oil spills, but the ocean wave often causes the boom’s overtopping failure. The Smoothed Particle Hydrodynamics numerical method which has advantages in simulating the free-surface-flows and the fluid-structure interaction was used to study the boom failure in the wave. A 2D wave flume model was constructed to simulate the wave acting on the boom which causes the boom’s overtopping failure. The effect of deflection angle of boom was systematically studied. Through comparing the critical height range of wave that causes the overtopping failure of boom at different angles, the optimal angle range for the efficiency of boom against wave which is-40° to-60° is proposed. SPH as a utility method for simulating the fluid-structure interaction problem has exerted its effectiveness in learning the overtopping behavior of wave acting on the boom.
