The study presents an axisymmetric laminar boundary layer flow of a viscousincompressible fluid and heat transfer over a stretching cylinder embedded in aporous medium. A suitable similarity transformation is employed to transformthe partial differential equations corresponding to the momentum and heatequations into nonlinear ordinary differential equations. The resultantordinary differential equations are then solved using a successive relaxationmethod (SRM). The effects of significant parameters on the velocity and temperatureprofiles have been analyzed graphically. The obtained results are also comparedwith previously published results in some special cases and were found to bein excellent agreement. The skin friction as well as the heat transfer rate atthe surface are increased as the values of the curvature parameter increase
