摘要

This communication reports the flow of a nanofluid near a stagnation-point towards a stretching surface. The effects of Brownian motion and thermophoresis are further taken into account. The analytic solutions are developed by homotopy analysis method (HAM). Special emphasis has been given to the parameters of physical interest which include stretching ratio a/c, Prandtl number Pr, Lewis number Le, Brownian motion number Nb and thermophoresis number Nt. It is observed that reduced Nusselt number is an increasing function of ratio ale The comparison of the present results with the existing numerical solutions in a liming sense is also shown and this comparison is very good.
