An analysis is presented to investigate the combined effect of the thermal radiation and the presence of an isotropic solid matrix on the forced convection heat transfer rate from a flat plate to a power-law non-Newtonian fluid saturated porous medium. The Forchheimer extension is also considered in the flow equations. The rosseland approximation is used to describe the radiative heat flux in the energy equation. Numerical results are presented for the velocity distribution and temperature profiles within the boundary layer. The effects of the flow index, radiation, first and second-order resistance on the velocity, and temperature profiles are discussed. The missing wall values of the velocity and thermal functions are tabulated.
