摘要
在近岸波浪数值计算中,动边界处理是不可避免的问题。文章基于Boussinesq方程的FUNWAVE-TVD模式,引入窄缝法对波浪水槽实验进行数值模拟,比较窄缝法和干湿网格法的波浪数值计算结果;设计多种周期和波高的波浪数值试验,分析两种动边界处理下数值计算结果的差异。结果表明,两种动边界处理对近岸波浪破碎的数值模拟有影响,对波浪漫滩区的计算影响尤为显著。
Moving shoreline is an inevitable issue in numerical calculation nearing the surf zone.This paper laid slot method to the fully nonlinear Boussinesq model FUNWAVE-TVD to simulate flume experiment,then compared with the numerical result of slot and wet-dry method.Besides,series numerical calculations were designed to analyze the result of two shoreline handling method.The results showed that the impact of moving shoreline on wave shoaling and breaking calculation is obvious close,especially in the calculation of swash zone.
