Abstract

The perforated caissons are widely used to decrease wave force and reflection effectively in costal engineering. The nonlinear interactions between waves and partially perforated caissons are investigated using the weakly compressible Smoothed Particle Hydrodynamic (WCSPH) method. An improved algorithm based on the dynamic boundary particles (DBPs) is proposed to treat the solid boundary. The performance of the model is validated by the analytical solution of the surface elevations and wave pressures in front of the vertical wall. The SPH results of the reflection coefficients of the perforated caissons are compared with the available experiment data and good agreements are obtained. The wave pressures on the perforated front wall and the rear wall are analyzed. The effects of the relative wave chamber width B/L_c and the porosity of the perforated wall on the wave energy dissipation of the perforated caissons are discussed.
