摘    要:从Navier-Stokes方程出发,采用VOF法追踪自由液面,基于流体计算软件FLOW3D,模拟宽广水域内滑块下滑所引起的涌浪及其传播过程,将数值结果与实验结果进行对比可知,计算值与实验值吻合较好.在此基础上,研究了涌浪产生时相同角度不同半径和相同半径不同角度测点位置的波高;并对涌浪产生后水体的流场结构以及自由液面的变化过程进行了研究.研究结果表明,该数学模型具有较高的精度和适应性,能较好地模拟滑坡崩落所导致的涌浪现象,对水库大坝设计及滑坡涌浪灾害预防具有一定的参考价值.

关 键 词:滑坡涌浪  VOF法  流场  自由表面  FLOW3D

Abstract:According to the N-S equation,the free surface elevation is tracked with VOF method,based on the fluid simulation calculation software FLOW3D water waves caused by the landslides and its propagation process,and numerical results are compared with experimental results.The result shows that the water waves caused by the landslides and its propagation rule can be well simulated by the numerical model.On this basis,the wave height of different angle located at the same radiu and different radiu located at the s...
Keywords:water waves caused by landslide  VOF method  velocity field  free surface elevation  FLOW3D
