摘要

摘要: 以N-S方程和k-ε湍流模型为基础,针对水温和盐度分层流的流动特性,考虑了浮力对紊动的影响,建立了温度和盐度分层流的k-ε模型,对同时存在温度和盐度梯度的一类密度分层流进行了数值模拟计算,其中紊动平均量控制方程中的紊动项是由k-ε紊流模型计算,给出了速度、温度和盐度的分布。计算结果正确地反映了分层及紊动特征,与实测结果吻合较好。

Abstract: Based on the N-S equation and the universal k-ε turbulent model,taking the character of therma and saline stratified flow and the effects of buoyancy on turbulence into account,the k-ε model of therma and saline stratified flow is established.Density stratified flow with both the vertical temperature gradient and the vertical salinity gradient is simulated numerically,in which turbulent terms are calculated by the k-ε turbulent model.The distributions of velocity,temperature and salinity are given in this paper.The feature of stratification and turbulence is described correctly by the rmdel.The computational results agree well with the experimental data.
