| 摘 要： | 建立了基于OpenFOAM动边界的类fixedValuePointPatchVectorField继承的仿物理造波数值波浪水槽。对孤立波在三种不同潜礁地形上的行进、爬坡以及破碎等典型过程进行数值模拟,模拟结果与Boussinesq模型及物理模型试验所得结果进行了对比分析。结果表明,采用动边界进行仿物理造波更适合处理波高水深比较大的孤立波传播问题,可以较好地模拟孤立波在潜礁上传播引起的波浪破碎、水跃等现象。

| Abstract: | Based on the class of moving boundary named fixedValuePointPatchVectorField in OpenFOAM, a piston-type wave generation boundary is developed by class inheritance. After that, the process of the propagation, run-up and breaking of a solitary wave over three diversiform reef profiles is simulated. Numerical results are examined, discussed and compared with the results of Boussinesq model and physical model test. It could be concluded that the present model could effectively handle the solitary wave that has a large ratio of wave height and water depth. Furthermore, the nonlinear process such as wave breaking and hydraulic jump could be also simulated well. |
