Abstract:为了获得具有更优性能的波浪传播数学模型,对一组近似到O(μ2)阶完全非线性的Boussinesq方程进行了改进,加强过程保留高阶非线性项,改进后的方程色散性能和非线性性能均有提高.该方程可以简化为多个以水深平均速度表达的二阶Boussinesq类水波方程.理论分析了加强对方程二阶非线性和三阶非线性的影响,并将其同传统加强方式进行了比较,结果表明,含高阶非线性项的加强方式得到的方程性能更好.基于该方程,在非交错网格下建立了基于有限差分方法的高精度数值模型.利用数值模型模拟波浪在潜堤上的传播变形,探讨了2种不同加强方式以及非线性对数值结果的影响,结果表明,加强过程保留高阶非线性的方程模拟结果更佳.
