摘要(Abstract):

介绍了基于对应态原理建立的氮烃类多元混合工质的统一粘度模型
Unified visconsity model based on corresponding states principle was used to predict viscosities of nitrogen and hydrocarbon mixtures.By introducing mixing rule,only limited thermodynamic data of each components were required as input and the calculation procedure was simplified.Comparisons between calculation and experimental data of binary light hydrocarbon mixtures and multicomponent hydrocarbon mixtures were presented,average absoulte deviations were 4.13% and 2.13% respectively.Significant improvement in accuracy was observed as compared with other viscosity model.
