• EFFECT OF FIRST ORDER CHEMICAL REACTION IN A VERTICAL DOUBLE PASSAGE CHANNEL FILLED WITH POROUS MATRIX

Abstract

This paper presents an analytical solution of dispersion of solute with first order chemical reaction in a vertical double passage channel filled with porous medium. The channel is divided into two passages by means of a thin perfectly conducting baffle. Approximate analytical solutions are found for the coupled nonlinear ordinary differential equations using regular perturbation method. The solutions are evaluated and shown graphically for thermal Grashof number, mass Grashof number, Brinkman number, porous parameter and chemical reaction parameter at all different baffle positions. It is found that thermal Grashof number, mass Grashof number, Brinkman number enhances the flow where as porous parameter and chemical reaction parameter reduces the flow at all baffle position.
