Catalyzed combustion is a low-temperature, flameless process that emits less nitrogen oxide. It also specifies flammability limits and reactor design constraints. Catalyzed combustion's advantages determine its potential applications. We present a numerical analysis of the catalyzed combustion of a methane-air mixture on a heated platinum channel wall. The cylindrical channel is modeled with 2D axisymmetric solver. The modeling is based on the “Species transport. The finite volume calculation code Fluent was used to create the various numerical simulations. Interesting findings have been made regarding temperature and the mass fractions of the various species involved in combustion, including methane (CH4), carbon dioxide (CO2), water (H2O), and nitrogen monoxide (NO) as sources of pollution issues.
