在任意温度和压力范围内真实分子通用状态方程的发展:I。核心参考系

Development of a general equation of state for real molecules in arbitrary regimes of temperature and pressure: I. The hard-core reference system

J. F. Kenney, Richard J. Petti

摘要:

本文从第一性原理出发,利用度量微分几何的统计力学论证,导出了真实流体的刚体参考系的通用状态方程,描述了刚体流体的“有效体积”V0及其决定面S0。Reiss等人的定标粒子理论的严格、精确的结果,它们本身是从统计几何学中获得的,在Boublik等人的扩展之后已应用于非球形的坚硬物体。在低密度和中等密度下,刚体系统的几何描述可以与Boublik状态方程一起使用。在高密度时,这种几何描述指定了指定V0和S0的过程,尽管两者都变成了多连通的。

英文摘要:

A general equation of state for the hard-body reference system of real fluid has been developed from first principles, statistical mechanical arguments using metric differential geometry to describe the "available volume," V0, and its determining surface, S0, of a hard-body fluid. The rigorous, exact results of scaled particle theory of Reiss et al., which themselves obtain from statistical geometry, have been applied following the extension of Boublik et al. for hard bodies of non-spherical shape. The geometric description of the hard-body system can be used with the Boublik equation of state at low and modest densities. At high densities, this geometric description specifies the procedure to specify V0 and S0, notwithstanding that both become multiply-connected.
