Study on Numerical Simulation of Contaminated Volume for ShutdownBatching Pipeline

摘要

Aimed at phenomenon of Shutdown Batching Pipeline, Setting up 3D unsteadyrnContamination Numerical Calculation modal, from mass and Momentum transferrncoupling, based on PHOENICS3.6 software. The Analysis of Numeric Examplesrnshows that the effect of Shutdown on Contamination, and Contaminationrnmechanism of former diesel oil – back gasoline under the upgrade and therndowngrade pipeline and so on.. Finally, in the different working condition, thernContamination effects of shutdown transportation are different, resulting in thernconcentration curve variety regulation of shutdown transportation
