振荡流底层悬沙运动的数值研究

Numerical simulation of sediment in oscillatory flow over plane bed

  • 摘要: 建立了平底振荡流底层立面二维水沙数值模型,利用Smagrionsky(SGS)格子涡模型封闭二维Navier Storkes方程水流运动方程组,控制方程采用SMAC法求解。该模型能较精确地模拟振荡流底层水流流动特性,以及含沙量沿垂线分布和随相位变化的情况,且与水槽实验的实测资料基本吻合。

     

    Abstract: A 2-D numerical model is developed to simulate flow and suspended sediment concentration in oscilating turbulent boundary layer over plane bed,which is based on the N-S equations with the Smagrionsky's subgrid-scale turbulence model The calculation results agrees well with the flow characteristic and sediment concentration measured in experiment practically.
