Abstract

This paper deals with heat and mass transfer in the magnetohydrodynamic flow of a visco-elastic fluid in a rotating porous channel with radiative heat. The flow phenomenon has been characterized by the fluid parameters like Hartmann number (Μ), rotation parameter (Ω), Reynolds number (λ), thermal Grashof number (G r ), mass diffusion Grashof number (G c ), non-Newtonian parameter (R c ), Prandtl number (P r ), Schmidt number (S c ), Radiative heat (R) and the permeability parameter (K p ). Introducing complex variable terms in the expansion of velocity function, temperature function and concentration function, solutions of the corresponding equations have been obtained. It is revealed from the characteristic profiles that the steady flow velocity rises with the G r and G c both. Increase in radiation parameter lowers the secondary flow velocity (f 1). The rise in the external magnetic field strength reduces the secondary flow velocity (f 2).
