The mixed convection flow over a sphere embedded in a porous medium has been studied by boundary layer analysis. Solutions for the transformed equations are presented by the Keller-box numerical scheme. Results for the velocity and temperature fields as well as friction factor and Nusselt number are presented for aiding and opposing flow conditions.
