摘要
导出了线性波浪作用于上部可渗透的直立刚性圆柱体上的水动力的解析解．在线性 有势流的假定下，用特征函数展开方法求出了内部和外部流场的解．给出了不同波浪要素 及结构尺寸参数下的数值结果．由结果可知，可渗透性可以大大减少波浪作用力．
Analytical solution to the interaction of linear water waves with a rigid vertical circular cylinder of porous in the vicinity of the free surface is derived. Under the assumptions of linearized potential flow, the coupled problem of flow in the interior and exterior fluid regions is solved by an eigenfunction-expansion approach. Numerical results are presented that illustrate the effects of the various wave and structural parameters on the hydrodynamics loads. For certain parameter combinations the porous circular cylinder may significantly reduce the hydrodynamic forces.
