| 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...

| 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 shu... |
