关于非线性船波问题自由面边界条件的讨论

Discussion of Free Surface Conditions of Nonlinear Ship Wave Resistance

文中主要分析讨论了船舶兴波问题的自由面边界条件。将自由面边界条件在未扰动的自由面上进行展开,利用量级分析而得到了新的慢船自由面边界条件,并与他人的自由面条件进行了比较。根据文中所得到的非线性自由面条件,用耦合元方法计算了wigly数学船型和系列60船型的兴波阻力,并与试验结果及他人的计算结果进行了分析比较。

This paper analyses and discusses the free surface conditions of ship wavemaking. The authors of this paper expand the free surface conditions, and obtain a new slow ship free surface condition by means of dimensional analysis, and compare the condition with others. Finally, it is proved by comparing the numerical results with test results and numerical results of others that the nonlinear free surface condition in this paper can simulate nonlinear ship wave better.
