Abstract
This paper presents the reactions and equations required for modeling the combustion mechanism of carbon monoxide. Some concepts of chemical kinetics are presented, such as reaction rates and steady-state and partial equilibrium approximations. Thereafter, the complete mechanism for combustion of CO is displayed and a reduction of the mechanism is made to reduce the rigidity of the system. The resulting system of ordinary differential equations is integrated by the four-stage fourth-order L-stable Rosenbrock method. A simulation of the reduced mechanism is made assuming very small initial molar densities for the species, with the exception of the reagents.
