建立封闭的双流体模型并对垂直管内油水分散流进行了数值模拟，采用k—ε模型处理连续相的湍流结构。模型预测结果与实验数据的比较结果表明，该模型能较好地模拟垂直管湍流分散流的局部相含率分布和速度分布。“,”Dispersed oil-water two-phase flow in vertical pipe is numerically simulated using two-fluid modelling approach. A k - ε model is applied for turbulent structure of continuous fluid. The Comparison of the experimental data to the present model prediction results show that the model can predict the local volume fraction and velocity profiles well.
