摘　　要：建立了顺序输送混油模型,利用PHOENICS软件对停输前后混油段浓度分布进行了数值模拟,并给出了混油浓度变化图象和曲线。结果表明,在竖直管道顺序输送过程中密度差对层流边界层的影响会表现的比较明显且大于粘度差的影响。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 of batch transportation was established. Numerical simulation for the concentration distribution of contamination before and after shut-down to Batch Pipeline has been investigated with the help of PHOENICS. The result is given by curves and pictures. The computation results showed that the effect of density to laminar bottom in erect pipeline is distinct and bigger than viscosity difference. The theory that 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 reduce contamination at shut-down and track contamination interfacial and incise on breaking down and restart of pipeline.
