ABSTRACT A multi-domain boundary element code is developed to study the effect of permeable plates for attenuating wave-induced response of a floating structure near a rigid wall. The physical problem is studied in two dimensions under the assumptions of linearized water wave theory in water of finite depth. It is observed that in the presence of permeable plates, the floating structure experiences a significant reduction in the amplitude of various hydrodynamic coefficients related to the diffraction and radiation of gravity waves. Interestingly, the negative added mass phenomena associated with the oscillating floating structure reduce up to 30% with suitable choice of the permeability of porous plates, space between them, and careful positioning between the structure and impermeable wall. The study reveals that significant reduction in the amplitude of resonating patterns in the hydrodynamics characteristics can be achieved in the presence of porous plates of moderate permeability within the range 20% to 30%.

存在渗透板时壁附近浮动结构的波致响应

摘要 开发了一种多域边界元代码来研究透水板对刚性壁附近浮动结构的波致响应衰减的影响。在有限深度水中线性化水波理论的假设下，从二维角度研究物理问题。观察到在渗透板存在的情况下，漂浮结构经历了与重力波的衍射和辐射相关的各种水动力系数的幅度的显着减小。Interestingly, the negative added mass phenomena associated with the oscillating floating structure reduce up to 30% with suitable choice of the permeability of porous plates, space between them, and careful positioning between the structure and impermeable wall.
