Abstract

In this paper, the results of the two-dimensional and axisymmetric modeling of the methane-air pre-mixed combustion with multi-step kinetics in a porous medium with continuous porosity change have been presented. In order to determine the thermophysical and thermochemical properties of species, the CHEMKIN II program and Basic information used. Continuity equations, Navier Stokes, gas and solid phase heat transfer equations, and chemical species governing equations are solved by using of finite volume method. The SIMPLE algorithm has been used for the relationship between speed and pressure. The burner under the studied includes two preheated and combustible areas. In this paper, we study the effects of divergence angle changes and length of burner preheating area on temperature profiles and emission of pollutants. The results showed that by increasing the divergence angle, the amount of NO contamination in the burner output increases dramatically, while by increasing the length of the preheating region, the amount of emission of this pollutant in the output decreases.
