Analysis of combustion of a porous medium. Master's thesis

Technical Report ·
OSTI ID:5848646
A numerical analysis of a heat transfer and combustion model for a porous medium within a circular cylinder is carried out. The basic mechanisms considered in the theory are: a carbon energy conservation equation, energy balance on air, and an oxygen mass balance equation, and an oxygen mass-balance equation. Heat-transfer mechanisms included in the model are conduction, convection, and radiation. A heat-generation term arising from combustion of the carbon is included in the model. Transport mechanisms for oxygen mass transfer are molecular diffusion and convective transport. The governing heat- and mass-transfer equations are solved numerically by the Galerkin formulation of the finite element method. The results show the effects of permeability, porosity, geometry, and initial condition on the behavior of the system.
