Abstract

This article investigates the interaction between oblique waves and rectangular porous structures (bottom standing and surface piercing) in the presence of ocean current. The study employs the Sollit and Cross model to analyze wave behavior past porous structures, utilizing both analytical (eigenfunction expansion method) and numerical (boundary element method) approaches to solve the boundary value problem. In the boundary-element method (BEM), the boundary value problems undergo a transformation into integral equations along the physical boundaries. These boundaries are then subdivided into discrete elements, leading to the formulation of a set of linear algebraic equations. Then, the impact of the geometry of structure and properties of porous material is analyzed. Also, the impact of following and opposing currents is discussed. The research explores wave reflection and wave forces on the porous structure, revealing higher magnitudes in the presence of surface piercing structure compared to bottom standing structures.

多孔结构在电流作用下的斜波散射

本文研究了洋流作用下斜波与矩形多孔结构（底部立波和表面穿波）之间的相互作用。研究采用 Sollit 和 Cross 模型来分析波浪经过多孔结构时的行为，利用分析（特征函数展开法）和数值（边界元法）方法来解决边界值问题。在边界元法（BEM）中，边界值问题沿物理边界转化为积分方程。然后，这些边界被细分为离散元素，从而形成一组线性代数方程。然后，分析结构几何形状和多孔材料特性的影响。此外，还讨论了顺流和逆流的影响。研究探讨了多孔结构上的波浪反射和波浪力，结果表明，在存在表面穿孔结构的情况下，波浪反射和波浪力的大小要高于底部立面结构。
