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,提出了顺序输送混油新的模型,并利用PHOENICS软件成功地对该数学模型进行了数值求解。分析了竖直管道顺序输送油品时,密度和粘度差对混油的影响,并给出了模拟结果。研究结果表明:密度对大落差管道顺序输送过程中层流底层的影响,比较明显,不可忽略。研究结果对于研究我国西部地形复杂地区的顺序输送管道混油问题具有理论指导意义。
The new model of contamination on the predict problems near the wall has been proposed. ted with the help of PHOENICS. The effects of d pipeline are analyzed and the results are given. Th nar bottom significance elevatio researc n difference pipeline is distin h on contamination of batch -turbulent model and the wall function that is used to Numerical simulation for this model has been investigaensity and viscosity differences on contamination in erect e study results showed that the effect of density on lamict and can not been ignored. The study has a theoretical pipeline in the hypsography area in East-China.
