摘　　要：基于OpenFOAM开源工具箱,植入动量阻尼方程和规则波动网格边界,形成可靠的三维动网格气液两相流数值波浪水槽,在设置斜率为1∶6的斜坡平台上,模拟了波浪在近岸带浅滩破碎区的气液两相流破碎演化过程。数值模拟结果与试验值吻合较好,对波浪在浅滩破碎区发生的变形、坍塌、周围气体变化等情况模拟完整,可为波浪破碎机理研究提供较好的数据支撑。Based on the OpenFOAM,the momentum damping equation and regular wave grid boundary are implanted to form a reliable three-dimensional moving grid gas-liquid two-phase flow numerical wave flume.On the slope platform with a slope of 1 6,the gas-liquid two-phase flow breaking process of waves in the coastal shallow bank surf zone is simulated.The numerical simulation results are in good agreement with the experimental values,and the simulation of wave deformation,collapse and ambient gas changes in the shallow beach crushing area is complete,which can provide good data support for the study of wave crushing mechanism.
