硬球液体平衡性质的替代方法

Alternative Approaches to the Equilibrium Properties of Hard-Sphere Liquids

M. Lopez de Haro, S. B. Yuste, A. Santos

摘要:

本文综述了单组分和多组分硬球流体结构和热力学性质计算的一些分析方法。对于结构性质,它们产生了一个物理上一致的配方,从而改进和扩展了已知的分析结果的打击乐Yevick理论。讨论了径向分布函数接触值的近似表达式和相应的解析状态方程。这种方法的相关系统,如粘性硬球和方井流体,以及它的使用与流体的微扰理论的扩展进行了简要说明。

英文摘要:

An overview of some analytical approaches to the computation of the structural and thermodynamic properties of single component and multicomponent hard-sphere fluids is provided. For the structural properties, they yield a thermodynamically consistent formulation, thus improving and extending the known analytical results of the Percus-Yevick theory. Approximate expressions for the contact values of the radial distribution functions and the corresponding analytical equations of state are also discussed. Extensions of this methodology to related systems, such as sticky hard spheres and square-well fluids, as well as its use in connection with the perturbation theory of fluids are briefly addressed.
