Study on the Two-dimension Numerical Wave Tank Based on Fluent

该文利用Fluent软件,采用VOF(流体体积)法,基于N-S方程和RNGΚ?ε湍流模型,通过C语言进行二次开发,模拟二维数值波浪水槽,并与理论结果对比验证数值水槽的准确程度,进而在数值波浪场中放置潜堤结构物,将模拟的数值结果与实测数据进行对比。试验结果验证了Fluent软件模拟二维数值波浪水槽及结构物的可行性与有效性,为深入研究数值波浪水槽内结构物的水动力特性奠定了基础。

In this paper,a two-dimension numerical wave tank is proposed based on the Fluent software by means of secondary development using C language.The N-S equations and RNGΚ？εturbulence model are used with the VOF method（volume of fluid）.The unstructured grid is divided by the pre-processing software ICEM（Integrated Computer Engineering and Manufacturing Code）.The simulated water surface in the wave tank is compared with the theoretical results to verify the wave tank.Then a structure is put into the numerical wave tank and the comparison between the numerical results with measured data shows the validity of numerical generated wave which is a good foundation for the further numerical study on the hydrodynamic character of structures in wave tank.
