从N S方程入手推导并建立了波浪和水流相互作用数学模型 .该模型耦合了波浪和水流之间的相互作用因素 ,统一描述了波浪、水流流场在波流边界层内、外的变化规律 ,同时引入了k ε紊动模型封闭了方程 .模型结果与实验数据比较结果表明 ,所建立的波浪水流全流场模型能很好地反映波浪、水流之间的相互作用特性 .
Based on the Navier-Stokes equations, a mathematic model of interaction between wave and water flow is deduced and established. This model couples the interaction between wave and water flow and describes the variation regularity of wave and water flow field in and out of wave boundary layer. At the same time, the k ε turbulence model was introduced to close the equation.The results of the model and the experimental data show that the established full flow field model can well reflect the interaction between wave and water flow.
