| 摘 要： | 文章对多船多墩柱相互作用问题提出了一个快速计算方法.该方法是将船体剖面用具有相等面积的等效矩形代替,并将流场划分为船底与水底之间的内场和船侧面之外的外场.对内场,采用简单的解析解;对外场,由于剖面是矩形的,所以可采用在船体水面周线上分布源汇的简单的源汇分布法.对内外场进行耦合匹配进行求解.直立柱体则相当于船底和水底之间间隙为零的情况,所以上面也可包括直立柱体的情况,这样该方法对多船多墩柱的问题可以给出简便快速的算法.通过与试验结果和数值结果的比较,验证了文中计算的有效性.

| Abstract: | A simple and efficient calculating method for multiple ships and piers in waves is presented.The method is approximating the ship section by a rectangle with the same area as that of the original ship section.Then,the flow field is divided into inner domain below the ship bottom and the outer domain beside ship hull.The velocity potential in inner domain is given by an analytic solution.The velocity potential in outer domain is expressed by a source-sink distribution along the contour of ship water area.The... |
