In this paper specious transport and gaseous combustion have been modeled numerically using computational fluid dynamics method. A cylindrical combustor burning methane (CH4) in air is studied using the eddy-dissipation model. Eddy dissipation combustion model has been coupled with the standard k-ɛ model to simulate this highly complex turbulent reactive fluid flow field. Effects of air and fuel velocities have been investigated on the reactant mass fractions, temperature and velocity profiles and NOX production.
