Thermochemical Characterization of a Combustion Front Propagation in Reactive Porous Medium: a New Experimental Device

Description in terms of physicochemistry and heat and mass transfer of the combustion front propagation in a reactive porous medium remains a challenge to science. The literature about this subject distinguishes two types of problems. The first considers only combustion of the gas phase inside an inert solid porous medium. In the second type, the solid phase reacts with the gas phase; Chemical reactions such as pyrolysis of the solid and, further oxidation of the residual carbon occur, accompanied by changes in the physical structure of the solid phase. The media are called noninert porous medium. This latter case corresponds to the combustion process considered in this work.
