Thermodynamic Properties of the Mars Atmosphere Evaluated by Saha and Thomas-Fermi Models

Abstract— In this work the thermodynamic properties (the full pressure P, the internal energy per unit mass E, the average ionization degree α) of mixture of gases, evaluated by the Thomas–Fermi model and ionization equilibrium (Saha) model, are compared. It was used the mixture of oxygen, carbon and nitrogen in the proportion of the Mars atmosphere. The range of state parameters: the average density ρ = 10-3÷10-7 g/cm3, the temperature Т = (1÷100) eV.

Index Terms— ionization equilibrium model, Saha model, Thomas–Fermi model, thermodynamic properties, mixture of elements, atmosphere of Mars.
