本文利用ｋε方程求解了粗糙床面上波浪、水流联合作用下紊流边界层的紊动结构． 分析的结果表明：在边界层内， 波浪和水流的耦合运动不是简单的线性迭加， 而是呈非线性特性． 波浪的存在在很大程度上影响了水流的流速分布， 然而， 水流对波浪的流速分布影响却很小． 数值解与实验结果吻合较好， 在不引入涡层粘度假设的情况下， 给出了粗糙床面上波浪、水流联合作用下紊动边界层的结构特性．
In this paper, the k-ε equation is used to solve the turbulent structure of the turbulent boundary layer under the combined action of wave and water on a rough bed. The results of the analysis show that in the boundary layer, the coupled motion of wave and water is not a simple linear superposition, but a non-linear characteristic. The existence of the wave has a great influence on the flow velocity distribution of the water flow. However, the influence of the flow on the wave velocity distribution of the wave is very small. The numerical solution agrees well with the experimental results. Without introducing the assumption of vortex viscosity, the structural characteristics of the turbulent boundary layer under the combined action of wave and water on a rough bed are given.
