Abstract

The hydrodynamic efficiencies of perforated plates arranged at different inclinations are assessed through experimental investigations. Wave absorption capability of the perforated plates is governed by the optimum porosity and the slope of the structure. The reflection and transmission characteristics of waves influenced by the perforated plate exposed to different incident wave conditions are analysed for different porosities and slopes. The modified predictive equation for estimating wave reflection for impermeable plate is derived through experiments. Better wave absorption is observed for a plate with 10 % porosity and 15° slope. The details of the effects of slope and porosity of the inclined perforated plate on the wave reflection and transmission are discussed in this paper.
