Abstract
The present article models the effects of thermal radiation and convective conditions in magnetohydrodynamic (MHD) flow of Powell-Eyring nanofluid. A nonlinearly stretched sheet has been used to create the flow. Novel features regarding Brownian motion and thermophoresis are retained. The change of nonlinear partial differential systems to nonlinear ordinary differential systems is done by using suitable transformations. The resulting nonlinear systems have been solved via convergent approach. Graphs have been sketched in order to investigate that how the temperature and concentration distributions are affected by distinct physical flow parameters. Skin-friction coefficient and local Nusselt and Sherwood numbers have been numerically computed and analyzed. Our observations depict that the temperature and concentration distributions are decreasing functions of Prandtl number. Moreover the temperature and concentration distributions are enhanced for larger values of heat and mass transfer Biot numbers. (C) 2017 The Physical Society of the Republic of China (Taiwan).
