中文摘要：

在分析现有波浪水槽模拟方法的基础上，提出一种基于FLUENT求解器的在计算波浪水槽时用于消波区的自定义能量函数，并将其应用于计算三维波浪水槽中。通过在求解器中加入该能量函数，并将其结果与实验结果进行对比，找出了最佳的能量函数中的变量系数，达到优化三维波浪水槽的目的。

英文摘要：

By analyzing the existing wave tank simulation method, an energy function used in the wave absorption area was of- fered when using FLUNET to simulate the 3-D tank. The energy function was put into the FLUENT solver, and the results were com- pared with experimental results. The optimal wave attenuation coefficient of energy function was decided through the compare. This method can be used to optimize the 3-D tank perfectly, and the simulation result is similar with experience result.
