Abstract
highly porous medium. The fluid viscosity is assumed to decrease exponentially with temperature.The boundary layer equations are transformed into a non-similar form using an appropriate nonsimilar variable ξ and a pseudo-similar variable η . The non-similar equations are solved using an efficient local non-similarity method. The effect of viscosity variation parameter on the heat transfer, skin friction and the velocity and temperature distribution within the boundary layer is investigated. The viscosity variation parameter, the viscous dissipation parameter and non-similarity variable are shown to have a significant effect on velocity and thermal boundary layer and also on the skin friction coefficient and heat transfer at the wall.
