• EFFECT OF MAGNETIC FIELD ON UNSTEADY CONVECTIVE HEAT AND MASS TRANSFER FLOW IN A VERTICAL WAVY CHANNEL WITH OSCILLATORY FLUX WITH RADIATION ABSORPTION

Abstract

We discuss the effect of chemical reaction on unsteady free connective heat and mass transfer flow in a vertical wavy channel under the influence of a transverse magnetic field. The unsteadiness in the flow is due to the oscillatory flux in the flow region. The coupled equations governing the flow, heat and mass transfer have been solved by using a perturbation technique with the slope d as the perturbation parameter. The expression for the velocity, the temperature, the concentration, the shear stress and the rate of heat and mass transfer are derived and are analysed for different variations of the governing parameters M, b, k and Q₁.
