| Abstract: | Premixed combustion in porous media differs substantially from combustion in conventional media. The difference is the strong heat transfer between the gas mixture and the porous medium. Combustion is accompanied by the coupling of reactive transfer and heat transfer. For instance, analytical models are given for theoretical analysis of methane-air combustion in a packed bed column of inert porous alumina. Analytical solution is got for the temperature distribution, too. Super-adiabatic combustion is confirmed in this paper. |
