The Calculating Method of Equation-of-state for Inert Gases

本文介绍了单原子气体在高温高压状态下的物态方程的计算方法,模型考虑了分子电离引起的气体粒子数变化和带电粒子间的库仑力作用.用该方法计算了2种常见的单原子气体,结果与文献报道的数据符合良好,计算量明显减少.可以在PC机上进行单原子气体的物态方程计算.

In this paper, the calculating method of equation\|of\|state (EOS) for inert gases under high temperature and high pressure is studied, and coded in Fortran language. This method could easily used in calculation of equation of state on PC. The number change of particles and the effect of Coulomb force between electrification particles is successfully considered in this model. By this method, EOS of two inert gases, helium and neon, is calculated, and the results are in agreement with the previous, but calculating times is more decreased.
