| 摘 要： | 基于刘忠波等(2004)推导的新型高阶Boussinesq方程,建立了预报-校正差分格式的数值模型。为考察该数值模型的适用性,针对较大坡度的潜堤上的波浪传播变形进行了数值研究。将数值结果与实验结果进行比较,二者较为吻合,验证了本文的数值模型,同时也说明本方程可用于模拟较陡地形的波浪变形。

| Abstract: | Based on the new high order Boussinesq equations derived by Liu et al(2004),a numerical model is established by using the finite difference method with predictor-corrector scheme.The ivestigation of applicability of the numerical model,numerical simulations were done upon the relatively steeper submerged bar.Comparisons between the numerical and the experimental results show the better agreement,which shows that the present numerical model could be used for the steeper slope conditions. |
