二元相互作用系数推算方法的发展

Development of binary interaction parameters

回顾了二元相互作用系数直接估算方法的研究进展,细致分析了这些推导方式的应用范围,理论基础,以及精度范围,以期获得更有通用性的二元相互作用系数的预测模型,以能更方便地计算混合工质相平衡,尤其是缺乏实验数据的体系。

A review of the research and progress in the direct calculation method of the interaction coefficient in the mixing rules of PR, SRK, PT equations of state was presented, including the analysis of the range of the application ,the theory base and the precision of the direct calculation. The efforts in this work were made to obtain the popularly predictive model of the interaction coefficient and to improve the calculation of the vapor and liquid equilibria, especially for the systems without experimental data.
