摘　　要：利用自主开发的naoe-FOAM-SJTU求解器构建三维数值波浪水池.naoe-FOAM-SJTU求解器是基于开源程序库OpenFOAM开发的两相流求解器.它以Navier-Stokes方程为控制方程,采用VOF方法捕捉自由面.所构建的数值水池具有完整的造波系统、消波系统以及波高探测系统,可以实现不同类型波浪的模拟.对所构建的三维数值波浪水池的原理和过程进行介绍,对小幅线性波、Stokes二阶波、斜向波以及不规则波进行了数值模拟,并将数值结果与理论解进行了比较,结果吻合的很好,说明基于naoe-FOAM-SJTU求解器构建的三维数值波浪水池具有较好的精度,可以为海洋工程流体问题的数值模拟提供有效的波浪条件.Three-dimensional numerical wave tank has been constructed hased on the new developed solver naoeFOAM-SJTU, which is a hydrodynamic solver developed based on the open source code library OpenFOAM. The Navier-Stokes equations are employed as the governing equations for the two-phase fluid and the volume-of-fluid （VOF） method are used for the free surface capturing. The present numerical wave tank has complete systems for wave generating, wave damping and virtue wave probes for collecting the wave elevations, and different types of wave can be modeled in this tank. The theories applied for construction of the numerical wave tank are introduced and the numerical simulation of the linear wave, the 2ha-order Stokes wave, oblique wave and irregular wave are carried out. The results are compared with corresponding analytical solution of wave theories. Good agreement implies the accuracy of the numerical wave tank, which can provide efficient incident wave condition for studying the hydrodynamic problems involved in ship and ocean engineering.
