摘要
本文以Navier Stokes方程为控制方程,用k ε模型来封闭湍流模型,采用VOF方法来跟踪波动自由表面,建立了二维垂向数学模型。并用解析解和实验数据对模型进行了验证。利用此数学模型模拟了在水位较浅,不发生越浪的情况下,孤立波在直立堤、斜坡堤、半圆型防波堤堤前爬高的过程,并对波面、速度场和压强场进行了比较。
In this paper, two dimensional numerical models are developed based on Navier-Stokes equations. The standard k-ε equations are used to close the Reynolds equations. VOF method is used to reconstruct the free surface. The models are verified by analytic and experimental data. Then the models are used to simulate the process of solitary waves runup and rundown on the seaward wall of a vertical breakwater, a slope breakwater and a semi-circular breakwater, in the case when wave cannot overtop the breakwater. The wave profiles, velocity fields and the pressure contour plots are also compared.
