"The objectives of this research was to develop new equations of state for binary and ternary mixtures of the N2-Ar-O2 system that are applicable for wide ranges of mixture composition The resulting equations and tables of properties will be used in commercial applications such as air separation and liquefaction. Prior methods for the calculation of mixture properties were reviewed and used as a basis for the formulation presented here. Extended corresponding states (ECS) methods were investigated for both binary and ternary mixtures of nitrogen, argon and oxygen. The accurate fundamental equations for the pure substance constituents developed previously in the Center for Applied Thermodynamic Studies were used in this research. All thermodynamic properties of the mixture are calculated using analytical derivatives of the extended corresponding states model developed in this work. Temperature dependent binary interaction parameters were optimized using thermodynamic data for N2-O2, N2-Ar, and O2-Ar mixtures. A new property calculation package has been designed to facilitate calculation of required thermodynamic properties of nitrogen-argon-oxygen mixtures such as enthalpy, internal energy, entropy, heat capacities, and velocity of sound."--Leaf i.
