The present paper deals with the effects of nanofluids and thermal radiation over a stretching/shrinking sheet. The governing differential equations are transformed into a set of non-linear coupled ordinary differential equations which are then solved using numerical technique with appropriate boundary conditions for various values of physical parameters. The effects of various physical parameters on the dimensionless velocity, temperature, and concentration profiles are depicted graphically and analyzed in detail. Favorable comparisons with previously published work on various special cases of the problem are obtained. The effects of various physical parameters on the local Nusselt number and local Sherwood number are also presented in the tabular form. © 2015, Springer Science+Business Media Dordrecht.
