摘要
在K-ε紊流模型和使用壁面函数法处理近壁区问题的理论基础上,建立了顺序输送混油新的模型,并利用PHOENICS软件进行管内顺序输送数值模拟,计算结果清晰地反映出管内两油品交界面处的对流扩散传质现象。重点分析了输送次序对竖直上坡管道与下坡管道混油的影响。
The new model of batch pipeline delivery contamination is established based on the K-ε turbulent model and the wall function used to predict problem near the wall. Numerical simulation for this model has been investigated with the help of PHOENICS software. The calculation results clearly reflect the convection dispersion mass transfer phenomenon at the interface of two oils. The impact of transportation order on contamination in uphill and downhill pipelines is analyzed.
