Abstract

Theoretical model of gaseous mixture useful for practical calculations that realizes conception of thermodynamic similarity for three-parameter potential (n–6) is proposed. The form of mixture state equation, method of parameter determination of n repulsion's steepness and other parameters needed for calculate, as well as a method for determining the energy of interaction of heterogeneous molecular data on the interaction of the pure components are explained. The potential parameters and other values are given for a large number of technically important gases required for the calculation of thermodynamic properties of mixtures of arbitrary composition.
