EQUATION OF STATE FOR FLUIDS OF HARD HETERONUCLEAR DIATOMIC AND SYMMETRIC TRIATOMIC MOLECULES

摘要

A model previously developed for the equation of state of linear homonuclear fused hard sphere fluids is generalized to fluids with heteronuclear molecules. The model only requires two parameters, which can be determined from the geometrical characteristics of the molecules, for which analytical expressions are derived. Results for fluids with heteronuclear hard diatomic and symmetric triatomic molecules agree with simulation data within their accuracy for almost all the fluids considered.
