| 摘 要： | 针对管道输送成品油时的混油量计算问题,采用多相流模型,建立顺序输送混油控制方程,采用有限体积法进行了数值求解。以0#柴油和90#汽油为输送介质,对成品油由上至下和由下至上流经Z型管的2种情况进行了数值计算。研究结果表明,成品油流经Z型管水平管段时,相对于管轴混油段呈不对称分布;在竖直管段,柴上汽下运行时混油量比柴下汽上运行时大;前汽后柴运行时截面的体积分数分布比前柴后汽运行时均匀。

| Abstract: | Aiming at the mixed oil quantity of pipelining products, mixed oil control equations of batch transportation was established based on multiphase flow model and finite volume method. The transportation mediums were 0^# diesel and 90^# gasoline. The numerical calculation was based on two cases, the product flows through a Z-tube from top to bottom and from bottom to top. The research shows that when it flowed through the horizontal section of a Z-tube, the distribution of mixed oil is not symmetric. In a vertical section, there are lager amount of mixed oil when diesel is above gasoline and the distribution of section concentration was more uniform when gasoline is in front of diesel. |
