Abstract

A new closed virial equation of state of hard-sphere fluids is proposed which reproduces the calculated or estimated values of the first 16 virial coefficients and at the same time gives very good accuracy when compared with computer simulation data for the compressibility factor over the entire fluid range, as well as having a pole at the correct closest packing density.

摘要

提出了一种新的硬球流体的封闭维里状态方程，它再现了前 16 个维里系数的计算或估计值，同时在整个流体范围内与压缩因子的计算机模拟数据相比具有非常高的精度，并且在正确的最密堆积密度处有一个极点。
