浮体在浅水中运动产生的孤立波

The Solitary Wave Generated by Moving Float-Bodyin Shallow Water

本文对在浅水中以跨临界速度运动的浮体产生的兴波同题作了数值计算,用作者提出的求解浮体波动问题的新方法,将浮体与流体接触的物面作为自由表面处理,使Boussinesq方程用于此问题的全域直接数值求解,数值结果使我们得到了新颖的浮体运动产生的孤立波解。

The wave generated by a float-body near the critical speed in shallow water is numerically studied in this paper. Based on our new numerical method of solving float-body problem, the wet surface of floating body is regarded as a part of free surface so that the Boussinesq equations can be used for whole computing region. As an example the numerical results of the solitary wave are obtained.
