ABSTRACT

            The effect of viscoelastic parameter on an unsteady hydromagnetic flow of a conducting optically thin viscoelastic fluid through a channel filled with saturated porous medium and non-uniform walls temperature are investigated in the presence of first-order chemical reaction and radiative heat transfer. It is assumed that the fluid has small electrical conductivity and the electromagnetic force produced is very small. Closed-form analytical solutions are constructed for the problem. The effects of the radiation and the magnetic field parameters on velocity profile and shear stress for different values of the viscoelastic parameter with the combination of the other flow parameters are illustrated graphically and physical aspects of the problem are discussed. 

Keywords: Oscillatory flow, porous medium, heat transfer, magnetic field, viscoelastic, first-order chemical reaction.
