AB - The effects of thermal radiation and heat transfer over an unsteady  stretching surface embedded in a porous medium in the presence of heat source  or sink are studied. The governing time dependent boundary layer equations  are transformed to ordinary differential equations containing radiation  parameter, permeability parameter, heat source or sink parameter, Prandtl  number, and unsteadiness parameter. These equations are solved numerically by  applying Nachtsheim-Swinger shooting iteration technique together with  Rung-Kutta fourth order integration scheme. The velocity profiles,  temperature profiles, the skin friction coefficient, and the rate of heat  transfer are computed and discussed in details for various values of the  different parameters. Comparison of the obtained numerical results is made  with previously published results.
