Effect of Reversible Reaction on Concentration Distribution of Solute in a Couette Flow

Abstract

A multiple-scale homogenization technique is employed in the current research to show the dispersion phenomena in a Couette flow where the solute may undergoes a reversible phase exchange between the immobile phase (stationary boundary bed phase) and mobile phase (fluid phase). Analytical solutions are obtained to view the influences of retardation factor and phase exchange kinetics on transport coefficient as well as in the two-dimensional longitudinal and transverse concentration distributions. Effects of several transversal position and dispersion time on longitudinal real concentration and the impact of different downstream stations on transverse concentration distributions are also determined. It is seen that with the increment of Damkohlar number the effective dispersivity reduces.
