Abstract


In this paper we investigate the radiation effect on the mixed convective heat transfer of viscous fluid through a porous medium confined in horizontal wavy channels which are maintained at non-uniform temperature in the presence of heat sources. The equations governing the flow, heat and mass transfer are solved using the perturbation technique with  d the slope of boundary as perturbation parameter. The velocity, temperature and concentration are analyzed for different variations of the governed parameters G, D-1, N and Sc. The shear stress and the rate of heat and mass transfer have been evaluated for different variations.
