Abstract
This article presents magnetohydrodynamic three-dimensional flow of nanofluid over an exponentially stretching surface with prescribed heat flux (PHF) and prescribed concentration flux (PCF) conditions. An exponentially stretching surface is used to generate the flow. Effects of Brownian motion, thermophoresis, viscous dissipation and Joule heating are also taken into account. Boundary layer and small magnetic Reynolds number assumptions are considered in the mathematical modeling. The conversion from nonlinear partial differential equations to nonlinear ordinary differential equations is taken into place by using suitable transformations. The resulting nonlinear system is solved via convergent homotopic approach. Graphs are sketched in order to analyze that how the temperature and concentration profiles are affected by distinct physical flow parameters. Skin-friction coefficients and local Nusselt and Sherwood numbers are also computed and analyzed. (C) 2017 The Physical Society of the Republic of China (Taiwan). Published by Elsevier B.V.
