Abstract

This paper proposes a mathematical model used to numerically simulate behaviors of the two-dimensional laminar
premixed combustion in porous media. The governing equations proposed include vorticity-stream function equations. This
set of the governing equations is non-dimensionalized and numerically solved based on finite difference algorithm. The
rectangular computational domain filled with saturated porous media is subjected to premixed reactant mixture coming into
the domain from the lateral wall. The top and bottom walls are insulated. The computation is conducted for half of the domain
based on a symmetrical boundary with appropriate flow and thermal conditions. The proposed mathematical model is
successfully validated against the published work. The computed results agree reasonably well with the previous work.
The model is able to correctly describe physical behaviors of a premixed combustion in which preheat, reaction and post
combustion zone are included.
