The study of the combustion in an annular combustor including the radiation heat transfer is presented. The study considers different models of combustion, the turbulence-chemistry interaction and the chemical kinetics. In the analysis a non-premixed, diffuse and turbulent model is considered, applying CFD (Fluent ®). The Chemical Equilibrium and Laminar Flamelet models are considered with one chemical mechanism to natural gas (methane). The results obtained show the radiation heat transfer effect on the temperature distribution in the combustor and compare the results obtained with both combustion models. The radiation heat transfer increases the temperature of the fuel and air input, modifying the temperature profile at the output of the combustor. On the other hand, the Laminar Flamelet model shows better results of temperature profiles at the output of the combustor, to be compared with results presenting in the literature.
