摘要： 基于FLUENT软件进行二次开发，得到了一个用于求解甲板上浪问题的完整的数值模拟方案.该方案融合了动网格功能、数值波浪水池的消波和推板边界造波、船体运动的自动求解、捕捉自由液面大变形的流体体积分数法、高效的网格划分方案和稳定精确的时间步长方案，最终实现了波浪和船体运动的耦合，成功模拟了甲板上浪现象，并将该方案应用到自由运动船体在顶浪状态下的上浪问题研究中，模拟得到了物体在波浪上的运动及甲板上浪的过程，同时还得到了上浪产生的冲击压力.

Abstract: Based on CFD software FLUENT, the secondary development was conducted targeting at a full solution for numerical simulation of green water problem. This solution consists of dynamic mesh, numerical wave tank integrated with piston type wavemaker and a dissipation zone, an automatic strategy for calculating ship motion, water surface capturing scheme——VOF method, high efficiency mesh plan and an accurate timestep. The solution was put into use on a freely moving ship in head wave. During the simulation, motion of the ship was calculated; and both the evolution process of green water and the impact load of green water were recorded.
