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.

通过实验研究评估了布置在不同倾斜度的多孔板的水动力效率。多孔板的吸波能力取决于最佳孔隙率和结构斜率。针对不同的孔隙率和斜率，分析了受多孔板影响的入射波在不同入射波条件下的反射和透射特性。通过实验推导了改进的预测防渗板波反射的预测方程。对于具有10％孔隙率和15°斜率的板，观察到了更好的波吸收。本文详细讨论了斜孔板的斜率和孔隙率对波反射和透射的影响。
