摘要
文中研究自由体积在流体的宏观性质,尤其是传递性质中的应用,给出了自由体积与Helmholtz自由能、过量Gibbs自由焓G^B等热力学基本量的关系;然后介绍了自由体积与流体传递性质间的关系,概述了有关模型;最后,论述了自由体积在联系平衡性质与传递性质间所起的桥梁作用,导出了流体纯物质及混合物传递性质的有关模型,为进一步的研究和应用提供基本方程和方法。
The statistical definitions of the free volume are reviewed with comments ontheir relations and differences, and then a general definition is given based on theperturbation theory. A rigorous correlation of the free volume with equations of state(EOS) is proposed and several representative equations are derived. Finally, different equa-tions for the free volume are compared with each other and some suggestions for furtherdevelopment of the models for both equilibrium and transport properties are discussed.
