A Computer Program for the Calculation of Adiabatic Flame Temperature and Equilibrium Chemical Composition in Constant Pressure and Constant Volume Systems.

This report presents a computer program for the calculation of the adiabatic flame temperature and equilibrium chemical composition of constant pressure and constant volume systems. It is capable of treating either hydrocarbon or hydrogen fuels with either air or pure oxygen as the oxidizing agent. A solution procedure is presented which is fast, accurate and numerically stable. Analytical heat capacity equations are used to generate required thermodynamic data, thus avoiding the necessity of storing and interpolating lengthy data tables. The technique lends itself to the easy inclusion of additional chemical species which may be of interest under certain circumstances. The ideal gas assumption is used throughout the analysis.
