ResumoAbstract. The structure of premixed flames within porous media is investigated by using the asymptotic expansion method. The flame is divided in three distinct regions. Two of them, the gas conduction region (also known as preheating region) and the reaction region, are the same two regions present in the classical premixed flame structure. The third region is related to the heat conduction in the solid matrix. Since the chemical reaction is very sensitive to temperature, the reaction occurs in a very thin zone inside the gas conduction region, where the highest gas phase temperature is found. Also, since the solid heat conduction is higher than the gas heat conduction, the solid phase heat conduction region is much thicker than the gas phase heat conduction region. Discrepancies in the characteristic lengths among the three regions justify the application of asymptotic expansions to determine an approximated (analytical) solution. The description of the reaction region is obtained using the large activation energy asymptotic expansion and the description of the preheating region is obtained usig the boundary layer expansion. The influence of the ratio of the solid- and the gas-phasic effective conductivities, intraphasic heat transfer coefficient and the porosity of the medium are evaluated, revealing the effects of the inner flame structure on the flame stabilization within porous media.
