基于开源程序OpenFOAM建立了三维波浪破碎数值模型，模型控制方程采用三维不可压缩粘性流体运动RANS方程，应用VOF方法捕捉自由表面，分别运用动量分布源方法、阻尼消波方法实现数值造波和消波，紊流模型选用RNG k?ε模型。利用所建立的三维波浪破碎数值模型模拟了破碎波对单桩结构物的作用力，并与物理模型实验数据进行对比分析。结果证明该模型可以较好地模拟近岸单桩结构物所受破碎波浪荷载。

A 3?D numerical model for breaking wave was developed based on the open source code Open?FOAM. The governing equations of the model are the RANS equations of the three?dimensional incompressible vis?cous fluid. The VOF method was used to capture the interface between air and fluid. The wave?maker of distributed momentum source and the damping wave absorption were applied in the momentum equations for generating and ab?sorbing waves respectively. The RNG k?εturbulence model was adopted. The presented model was used to simu?late the breaking wave force acting on the pile on a beach. The numerical results were compared with the previous experimental data. It is shown that the model is of sufficient accuracy to simulate the breaking wave force on mono?pile in shallow water.
