ABSTRACT: In this work, it was simulated the combustion process in a high velocity chamber, which uses highly preheated air and methane as fuel. The simulation carried out with FLUENT grid drawn GAMBIT. These programs were used designing tool to predict performance of system when two different types burners are tested, there is not swirl generation. first type burner fuel injected axially. second one radially. models were: k - e for turbulence, P1 radiation PDF-Mixture Fraction processes. numerical results show that radial injection presents better than axial regard efficiency, also achieved more complete due mix between .
