摘要
船舶运动格林函数因其良好的远场波状特性以及自动满足线性自由面边界条件和辐射条件 ,在求解船舶运动问题的线性理论中扮演着重要的角色 .而对船舶运动格林函数的数值计算非常复杂和耗时 ,这阻碍了船舶运动格林函数在求解船舶运动问题中的进一步应用 .文中提出了按区域计算船舶运动格林函数的一种方法 ,对船舶运动格林函数的远场部分在近场区域进行了数值计算 ;
Ship motion Green function plays a critical role in linearized theory of resolving ship motion problem due to it's intrinsic properties such as proper far field wavy behavior and automatically fulfilling radiation condition and linearized free surface boundary condition. Numerical analysis of ship motion Green function is very complex, this is the major stumbling block hindering the further application of ship motion Green function. In this article, a method of computing ship motion Green function according to different domain is proposed, and the far field components of ship motion Green function are calculated with this method in near field. It is shown that this method can reduce computing burden.
