摘要
本文以平均速度势表示的Boussinesq方程为控制方程,采用谱分析方法,研究了孤立波对直立大椭圆柱的绕射计算问题。文中提出了一种在使用谱方法解方程的同时满足椭圆边条件的简捷而有效的方法。最后给出了攻角为0°和90°两种情形下孤立波对直立大椭圆柱绕射的波浪力系数曲线。
The spectral method is used in this paper to compute the diffraction of a solitary wavce around a large vertical elliptical cylinder, which is described by the Boussinesq equations expressed in depth-averaged velocity potential、A new way is found, which is simple and efficient in dealing with elliptical boundary. The wave force coefficients with attack angle of 0°and 90°?are also given at the end of this paper.
