In order to study the mechanism of low NO_X emissions and combustion characteristics in Stagnation Point Reverse Flow (SPRF) combustors, Computational Fluid Dynamics (CFD) method was employed to simulate the combustion process in a SPRF combustor. The distribution and variation of the major species, flow characteristics, pollutant emissions (CO and NO) were presented and discussed. Results showed that the reaction zone occupied approximate one third of the combustion chamber, resulting in much lower pollutant emissions. This implies that SPRF combustors work in flameless mode. Besides, the simplified two step methane oxidation mechanism combined with post-process technique to calculate NO emission has the capability to model the combustion process and pollutant emissions in SPRF combustors.
