Gas flow through porous media is characterized by large vortex structures and large friction coefficients, resulting in an extensive momentum and interphase energy exchange between gas and the solid phase. The model used for flow in porous regions is at once both a generalization of the Navier-Stokes equations and of Darcy's law commonly used for flows in porous regions. The model retains both advection and diffusion terms and so can be used where such effects are important. In deriving the continium equations, it assumed that 'infinitecimal' control volumes and surfaces are large relative to the interstitutal spacing of the porous medium, through small relative to the scales that we wish to resolve. Thus, given control cells and control surfaces are assumed to contain both solid and gas regions. Based on this model, an efficient numerical technique has been developed and a numerical algorithm has been produced to study the processes in the porous medium channel.
