Forced convective heat and mass transfer in a bidisperse porous parallel-plate channel with a first order reaction on the wall

Abstract The fully developed forced convective heat and mass transfer in a parallel-plate channel occupied by a bidisperse porous medium is investigated under the Darcy flow model and the constant heat flux boundary condition. The first order catalytic reaction is assumed to be taken place on the walls. Analytical solutions are sought for the temperature and concentration of two phases using the direct decoupling approach. The effects of Darcy velocity ratio, effective thermal conductivity ratio, inter-phase mass transfer coefficient, Biot, Damkohler and Soret numbers are investigated on the temperature and concentration distributions.
