| 摘 要： | 在一维的Boussinesq方程中引入表面翻滚的概念,通过附加迁移动量项来考虑浅水中的波浪运动以及破碎情况,建立数学模型。利用此数学模型对Airy波和孤立波在浅水中运动以及破碎情况进行模拟,得出的结果与Schoiffer和Goda的结果比较,吻合良好。

| Abstract: | A simple description of wave breaking in shallow water is incorporated in the Boussinesq equations using the concept of surface rollers.The roller is considered as a volume of water being carried by the wave with the wave celerity.The effect of the roller is included in the vertical distribution of the horizontal velocity,which leads to an additional convective momentum term.The numerical simulation is applied to the Airy wave and solitary wave running and breaking in shallow water.Some significant conclusions are obtained,and the numerical results are in good agreement with the achievements of Schffer and Goda. |
