| 摘 要： | 研究了大深度分层流体中二维任意形状淹没浮体的波浪力特性。首先基于一种合适的格林函数,采用边界积分方程法研究了流体中浮体对水波散射问题,然后通过单个淹没圆柱体的透射能和反射能与解析方法结果的比较,对所提出的方法进行了验证,最后分析了在不同的几何和物理条件下几种形状的浮体对波浪力的特有影响,得到了一些有意义的结果,这对分层海洋中淹没浮体的设计具有重要的参考价值。

| Abstract: | The characteristics of wave forces acting on a two-dimensional submerged floating body with arbitrary shape in layerd fluid are considered.On the hasis of appropriate Green functions, boundary integral equation method is used to analyze the problem of water waves scattered by the floating body.After the correctness of this method was verified by a comparison of reflection and transmission coef icients on a submerged circular cylinder with those obtained by an analytical method, the wave forces acting on cylinders with special shape were analyzed in two-layers fluid for some different geometrical and physical conditions, and some important results were got which are useful for the design of the ocean engineering structures. |
