摘要
回顾近期关于流体混合物热物性混合法则的研究新进展,特别是余吉布斯自由能(GE)和余亥姆霍兹自由能(AE)型混合法则的拓展及应用,重点介绍一种基于AE,仅通过偏微分方程便可计算混合物所有热力学性质的混合法则。可为发展未知流体混合物热物性计算方法以及各种常见混合物热物性的工程应用提供参考和依据。
The recent progress on mixing rules for thermodynamic properties of fluid mixtures had been reviewed. The excess Gibbs free energy （ G^E） and excess Helmholtz free energy （A^E） models coupled with various equations of state （EOS） and their applications to complex fluid mixtures systems were highlighted. The one based on A^E was highly recommended, by which all the thermodynamic properties can be calculated from the Helmholtz energy differential with respect to reduced density or temperature. This review could be helpful to the prediction of properties of general and even unknown fluid mixtures in the industry systems.
