Numerical Study of Reacting Flow in a Methane Burner with a Detailed Reaction Mechanism

In this paper, a numerical study of reacting flow in a methane burner using the Reynolds Averaged Navier-Stokes equation (RANS) is presented. A shear-stress transport turbulence model and presumed shape probability density functions (Pdfs) are used. Detailed chemical kinetic mechanism for the methane oxidation with 100 species and a 448 steps reaction has been developed using EXGAS software in this study. Moreover, simulations have been carried out to investigate the applicability of this study. The predicted temperature profiles agreed well with those obtained from Gas Research Institute (GRI) mechanism and the available experimental data. Other variables including CO2 predicted by the GRI and the EXGAS mechanisms also show good agreement
