PARTITION FUNCTIONS AND THERMODYNAMIC PROPERTIES OF HIGH TEMPERATURE GASES,

Abstract

Assuming a mixture of perfect gases consisting of atoms, molecules (neutral and singly ionized), negative atomic ions, electrons and up to four positive atomic ions, the equilibrium composition, internal partition functions and thermodynamic properties of argon, nitrogen and oxygen plasma were calculated by the methods of statistical mechanics for six pressures (0.01, 0.1, 0.5, 1.0, 2.0 and 5.0 atmospheres) at 100 K increments for temperatures up to 35000 K. Tables and figures include internal partition functions for all heavy species, chemical composition, mass density, entropy, internal energy, enthalpy Gibb's and Helmholtz free energies, specific heats at constant pressure and volume, the effective gamma and equilibrium sound speed.
