摘    要:本文从完整的N—S方程出发,采用修正的K—ε模型封闭雷诺方程,作为紊流控制方程,并采用VOF方法跟踪波动自由表面,依据所建立的数学模型与计算程序,对孤立波在岸滩上的传播与破碎的复杂过程进行了数模,并与实验结果进行了对比,二者吻合良好。

关 键 词:波浪,紊流,自由表面,不规则边界

Abstract:To solve the problems of irregular boundaries and free surfaces in predicting the motion of wave,a modified K-εturbulence model is derived,and the governing equations of turbulent flow over irregular boundary are developed by analyzing the solid-liquid two-phase theoretical flow model.And furthermore a partial- cell parameter is introduced to treat irregular boundary.To track. free surfaces, a simple but powerful method is described that is based on the concept of a fractional volume of fluid (VOF).The wave running up a beach has been simulated.The calculated run-up height is consistent with that of the experiment.
Keywords:Wave Turbulence model Partial-cell parameter Free surface
