Chemical Kinetic Modeling of Methane Combustion

In this work, we have developed a chemical kinetic modeling of methane combustion using a detailed kinetic mechanism including 213 elementary reactions and 48 species from literature. The mathematical model consists of a system of coupled ordinary differential equations resulting from kinetic rate laws. The solution is performed with a computer code in FORTRAN language based on the numerical fourth order Runge-Kutta method. The results show that the kinetic model used predicts efficiently the consumption of methane and oxygen as well as the production of water and carbon dioxide. However, the predicted nitrogen oxide formation (atmospheric pollutant) was less than the observed value.
