Abstract. Fluid flow and heat-transfer in a porous medium over a stretching surface have been investigated. The flow is influenced by linearly stretching the surface with internal heat generation or absorption and by the presence of suction, blowing and impermeability of the surface. An analytical solution for this flow is utilized and two cases are studied, namely, (i) constant surface temperature (CST case) and (ii) prescribed surface temperature (PST case). The effects of Prandtl number, permeability parameter, suction/blowing parameter and heat source/sink parameter on both flow and heat-transfer characteristics are studied and the variations of dimensionless surface temperature with various parameters are graphed and tabulated.
