摘要： 基于顺序输送混油理论,建立冷热原油顺序输送混油控制方程。借助计算流体动力学软件
FLUENT,对顺序输送管道停输前后混油体积分数的分布规律进行数值计算。分析了输送顺序对停输过程混油体
积分数的影响。研究表明:水平管段顺序输送停输后,受惯性力的作用,后续原油继续前行,使混油段增长且随着停
输时间的延长,采用前俄后庆的输送方式比前庆后俄输送混油段长。对于竖直管段,在相同条件下与水平管段相比
混油长度相对较短。采用前俄后庆的输送方式与前庆后俄输送混油长度接近,但前者混油体积分数分布比较均匀。
可为工程实际应用提供一定的理论指导。

Abstract:  

Based on contaminated product theory, contaminated product control equation on cold and hot crude oil was established. Using FLUENT, concentration distribution of contaminated product before and after shutdown was analyzed by numerical calculation. So was the impact on the concentration of contaminated product. The results show that the trailing oil product keeps going under the influence of the inertia force after shutdown of the horizontal pipe section, which makes the mixed contamination plug grow with the shutdown time extended. The mixed section is longer if the crude oil from Russian is transported before the oil from DaQing. The mixed section of the vertical pipe is longer than that of the horizontal section. The length of the mixed sections almost the same in both ways, but the concentration distribution of contaminated product is more evenly in the former. The results match well with the actual, which can provide a theoretical guide to practical applications for projects.
