Abstract

In the present paper, the wave absorbing performance of the fully submerged horizontal porous plates has been investigated numerically and experimentally. The submerged porous system is composed of multi-layered horizontal porous plates that are clamped at the vertical seawall, which are slightly inclined and placed in parallel with spacing in vertical direction. The hydrodynamic interaction of incident waves with the rigid porous multi-layered plates was formulated in the context of linear wave-body interaction theory and Darcy's law. The accuracy and convergence of the developed numerical codes were cross-checked based on the energy-conservation formula for a limiting case, and the comparison with the experiment in a two-dimensional wave tank. It is found that triple horizontal porous plates with slight inclination can. if it is properly tuned for wave energy dissipating against the standing waves in front of the vertical wall, have high performances in reducing the reflected wave amplitudes against the incident waves over a wide range of wave frequency.
