- Heterogeneous combustion, otherwise known as combustion in porous media, is a type of combustion in which a solid and gas phase interact to promote the complete transfer of reactants to their lower energy potential products. In this type of combustion a high surface area solid is immersed into a gaseous reacting flow, additional fluid phases may or may not be present. Chemical reactions and heat transfer occur locally on each phase and between both phases. Heterogeneous Combustion differs from catalysis as there is no focus to either phase individually but rather both examined simultaneously. In some materials, such as silicon carbide (SiC), oxide layers, SiO and SiO2, which form on the surface enable the adsorption of water vapor from the gas phase onto the solid lowering partial pressures. In this regime of combustion, thermal heat released from the combustion byproducts are transferred into the solid phase by convection; conduction and radiation both then conduct heat upstream (along with adverse convection within the gas phase). Heat is then convectively transferred to the unburnt reactants. (en)
