摘要: 依据雷诺方程和k-ε紊流模型,按流体体积(VOF)法追踪波浪自由表面,采用源造波法,建立数值波浪水槽,数值模拟波浪对复杂结构形式海堤的作用.数值模拟结果与经验公式、物理模型试验结果基本符合,说明所建立的数值波浪水槽合理可行.揭示了不规则波作用下复杂结构形式海堤波浪力分布规律,模拟了堤前波浪形态变化,为探讨合理的海堤结构形式提供了依据.Abstract: A numerical wave tank is developed to simulate the interaction between waves and complicated composite seawalls.In the wave tank,the Reynolds equations and the k-turbulent model are solved numerically,the volume of fluid(VOF) method is used to track free surfaces,and the source generation of waves is applied.Being compared the numerical results with the empirical solutions and the experimental results,it can been found that this numerical wave tank works well.The distribution of the wave pressures on the complicated composite seawalls under the condition of irregular waves is pointed out.The wave motions in front of the seawalls are simulated.It is useful for suggesting the reasonable type of the seawalls.
