摘 要：An analysis has been carried out to study the effects of radiation absorption and firstorder chemical reaction on unsteady mixed convective flow of a viscous incompressible electrically conducting fluid through a porous medium of variable permeability between two long vertical non conducting wavy channels in the presence of heat *** unsteadiness in the flow is due to traveling thermal wave imposed on the *** governing equations are solved subject to the relevant boundary conditions with the assumption that the solution consists of a mean part and a perturbed *** zeroth-order,the first order and the total solution of the problem are numerically evaluated and displayed graphically for pertinent *** model finds applications in studying fixed-bed catalytic reactors and packed bed heat exchangers.
