摘要
一般边界造波法只是用来生成线性波,至于边界造波法对不规则波、孤立波和强非线性波等是否适用,并没有做过多分析与研究。基于线性波、二阶Stokes波以及孤立波的速度和波形解析表达式,采用边界造波法,借助FLUENT软件中的用户自定义(UDF)功能,通过二次开发在FLUENT中实现波浪的模拟,并对它们的数值解与解析解做出比较,以此来验证边界造波法的适用性。计算结果表明,该数值水槽能有效模拟这三种波浪。
General boundary of waves is used to generate linear waves,as the boundary of waves on the irregular waves,solitary waves and strong non-linear wave,it applies not done much analysis and research.Based on speed and wave analytical expression of linear wave,second-order Stokes wave and solitary wave,boundary waves with the help of FLUENT software＇s user-defined（UDF） feature,through the secondary development implemented in FLUENT wave simulation,and their numerical solution and analytical solution to make more,in order to verify the applicability of the boundary of waves.The results show that the numerical simulation can sink the three waves.
