A novel iterative analytical solution is developed to study the oblique wave interaction with a horizontally submerged perforated plate near a partially reflecting vertical wall. The boundary condition on the perforated plate is considered as a quadratic pressure drop to incorporate the effect of wave height on the wave energy dissipation. The boundary value problem is analyzed analytically under the assumptions of small amplitude wave theory. To validate the analytical model, an iterative solution based on MBEM (multi-domain boundary element method) is independently developed, and the comparison between the analytical solution and the experimental data are given. The performance characteristics of a submerged perforated plate before a partially reflecting vertical wall is studied by analyzing the hydrodynamic coefficients of the system for the effects of plate porosity, relative plate width, spacing, depth of submergence, and the direction of wave attack. The proposed model is expected to act as an effective breakwater in the attenuation of wave energy for the creation of a tranquillity zone in the marine environment. Moreover, the analytical model developed in the present study can be effective and reliable for practical preliminary design.

斜波与部分反射垂直壁附近的水平多孔板的斜波相互作用的分析研究
开发了一种新颖的迭代分析解决方案,以研究与水平浸没的多孔板在部分反射的垂直壁附近的斜波相互作用。穿孔板上的边界条件被认为是二次压降,其中包含了波高对波能量耗散的影响。在小振幅波理论的假设下,分析了边值问题。为了验证该分析模型,独立开发了基于MBEM(多域边界元法)的迭代解,并给出了解析解与实验数据的比较。通过分析系统的流体力学系数,研究板的孔隙度,相对板宽度,间距,浸没深度和波侵袭方向,从而研究了在部分反射垂直壁之前浸没多孔板的性能特征。所提出的模型有望在波能衰减中起到有效的防波堤作用,从而在海洋环境中形成一个宁静区域。此外,在本研究中开发的分析模型对于实际的初步设计可能是有效和可靠的。所提出的模型有望在波能衰减中起到有效的防波堤作用,从而在海洋环境中形成一个宁静区域。此外,在本研究中开发的分析模型对于实际的初步设计可能是有效和可靠的。所提出的模型有望在波能衰减中起到有效的防波堤作用,从而在海洋环境中形成一个宁静区域。此外,在本研究中开发的分析模型对于实际的初步设计可能是有效和可靠的。
