A Combustion and Heat Transfer Model for Porous Media

Abstract

A general combustion and heat transfer model for porous media subject to Darcy flow is formulated. The transient one dimensional model treats the combustion process in two phases. During the initial phase, combustion occurs within the porous medium. The second phase occurs when the exothermic reaction moves to the air inlet surface of the medium resulting in surface recession. The temperature dependency of the system parameters and thermophysical properties is taken into account. An analysis of combustion in a carbon porous medium is presented, as well as an assessment of the accuracy of the model.
