Thermodynamic Modeling Of Combustion Synthesis

Abstract

This paper describes a summary of the basis of the thermodynamic variables with their equations, the thermodynamic models with their equations, the thermodynamic modeling software with their databases, the thermodynamic background of the combustion synthesis (CS) process with some examples. The integral molar Gibbs free energy change of mixing (ΔG M ) is the most important thermodynamic quantity. There are several models to calculate and minimize ΔG M . The calculation of ΔG M can be very difficult if there are several components in the identified process. The thermodynamic computer packages (software and their databases) enable the calculation of complex equations with high accuracy. Adiabatic temperature (Tad) is one of the parameters essential for the self-propagation of combustion synthesis. The comparison of the most common thermodynamic modeling software was introduced in this study. The results of some of the experimental studies about the CS process were also given in the concept of this study.
