摘要：
In this study, combustion in a 5kW porous burner is simulated. The two dimensional Navier-Stokes, the energy and the chemical species transport equations are solved and a multistep kinetics mechanism (5 reactions and 7 species) is employed. Finite volume method is used for simulation. Thermal nonequilibrium is accounted for gas and solid temperature and radiation heat transfer is considered for solid phase. Gas and solid temperature profiles and species mole fractions on the burner centerline are presented. Calculated CO and NO emissions are compared to experimental data for several excess air ratios. The effects of excess air ratio and solid phase radiation are investigated. The predicted temperature profile and pollutants formation are in good agreement with the available experimental data.
