摘　　要：建立了原油顺序输送混油模型,利用PHOENICS软件进行了数值模拟,并得出了混油浓度变化图象和曲线。表明在原油管道顺序输送过程中粘度差的影响,给出了不同管道倾角条件下浓度场的分布;同时也验证了停输时,密度大的油品在管道下方所形成混油段长度无明显增大现象且小于油品以相反的方向输送时所形成的混油段长度。研究结果对于减少停输工况下的混油与停输再启动混油界面的跟踪与切割具有理论指导意义。The contamination model for batch transportation of crude oil was established. Numerical Simulation for the concentration distribution of contamination in Batch Pipeline has been investigated with the help of PHOENICS. The result is given by curves and pictures. The computation results showed the effect of viscosity difference in crude pipeline. The theory that crude oil with smaller density is in bottom of pipe forming the length of contamination is not obvious and shorter than contrary direction at shut--down was also testified. The study has the theoretical guidance significance to reducing contamination at shut--down and tracking and incising contamination interface on breaking down and restart of pipeline.
