| 摘 要： | 基于雷诺平均Navier-Stokes方程和连续性方程建立适用于波浪与水流相互作用的三维数值波浪水池,并在该数值波浪水池内对立柱周围的波浪爬升效应进行数值模拟;选用不同的波流组合方式,探讨了水流速度对柱体周围的波浪爬升效应及其所受载荷的影响,并与波浪单独作用时立柱周围的波浪爬升情况进行对比,分析了水流对柱体周围波面的扰动和水质点运动轨迹的影响.同时,对波浪单独作用下,立柱近壁面处的波浪爬升效应进行了模型试验,以验证数值计算结果的准确性.结果表明,其计算值与试验值吻合较好.

| Abstract: | A 3D numerical wave tank suitable for wave-current interactions was created based on Navier-Stokes equations and continuity equations. The wave diffraction and run up effects were simulated in this numerical wave tank. Different wave-current combinations were selected to investigate the current effect on wave disturbance and trajectory of water particles. In order to verify the accuracy of the numerical calculation, a model test on wave run-up in wave alone condition near column wall was conducted. The results show that the values of calculation and model test are in good agreement. |
