摘　　要：油水两相混合物流经T形管路时,会产生流量分配不均、相含率和相分布重新分配的现象,此特性可用于多相混合物的分离作业。采用欧拉多相流模型和混合-湍流模型,研究了T形管垂直分岔次数、入口混合流速、入口含油率和流量配比等参数对T形管路中油水分离效率的影响。计算结果表明:增加分岔次数有利于油水分离;流量配比存在较优区间;较低的入口混合流速和入口含油率有利于提高分离效率。这些结论对T形管路结构优化和提高油水分离效率有重要的指导意义。When oil-water two phase mixer flows through T-shaped pipeline,non-uniform flow distribution,and redistribution of phase volume fraction and phase distribution can occur,and this characteristic is more used in separation operations of multi-phase mixture.This paper analyzes the influence of parameters (such as vertical bifurcation number,mixing flow rate at inlet,oil-content at inlet and flow-rate proportioning,etc.) on oil-water separation efficiency in T-shaped pipeline with Euler multiple-phase flow model and mixing κ-ε turbulence model.The calculation results show that increasing the bifurcation number is available for oil-water separation.There is better range for flow rate proportioning.And the lower mixing flow rate and lower oil content at inlet are helpful for the improvement of separation efficiency.These results will be of significance in guiding structure optimization and oil and water separation efficiency.
