Analytical Representation of the Thermodynamic Properties of Combustion Gases

This paper deals with mathematical equations for compressibility factor, enthalpy, and entropy of real combustion gases. These equations are approximated representations of the thermodynamic properties of burned gases, including low and high temperature behavior and hence the effects of molecular forces and dissociation. A suitable system in FORTRAN based on the equations, is programmed to resemble a series of charts for burned mixtures so that the same variety of data can be obtained much faster than by manual calculation.
