Oblique wave scattering by porous structures in the presence of current
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.
