In this paper a powerful and relatively new semi-computational method, DTM-Padé simulation is employed to study boundary-layer stagnation-point flow over a stretching sheet in a porous medium saturated by a nanofluid. DTM-Padé combines the differential transform method (DTM) and the theory of Padé approximants. Detailed solutions are presented and validated numerically with an optimized Runge-Kutta shooting method. The mathematical model includes internal heat generation/absorption and suction/injection effects. The velocity, temperature and concentration profiles are presented graphically for the effects of permeability parameter, thermophoresis parameter, Brownian motion parameter, transpiration (lateral mass flux i.e. suction/injection), heat source/sink parameter, Prandtl number and Lewis number. The present study is of relevance in energy materials processing technology and spacecraft thermal control systems.
