| 摘 要： | 越浪一直是波浪水动力问题的一个难点,原因在于其形成受到多种强非线性现象的作用。应用一种新型数值波浪模型(0-1BEM+VOF耦合模型)对越浪过程进行研究分析,并探讨了湍动动能、动能耗散率及流场在周期内的变化趋势。 |
| 关 键 词： | 越浪 0-1 BEM+ VOF 耦合模型 湍动 流场 |

| Abstract: | The overtopping is a complex phenomenon of gravity wave dynamics,including many nonlinear processes.Using a new coupling numerical model (0-1BEM+VOF),we study systematically the characteristics of flow field and turbulence during the overtopping process,and probe into the variation trend of the flow stream,velocity vector,turbulence kinetic energy and dissipation rated within a wave period. |
| Keywords: | overtopping 0-1 BEM + VOF coupling numerical model turbulence flow field |
