Description
Summary:•Magnetohydrodynamic (MHD) nonlinear convective flow of Powell-Erying nanofluid is modeled.•Velocity via fluid parameters (i.e., α and Λ) is quite opposite behavior.•Larger thermal conjugate parameter Bt yields temperature enhancement.•Opposite behavior of concentration field is noticed in view of Nb and Nt.•Reduction in local Nusselt number is observed for thermophoresis parameter Nt. Objective of present article is to describe magnetohydrodynamic (MHD) non-linear convective flow of Powell-Erying nanofluid over a stretching surface. Characteristics of Newtonian heat and mass conditions in this attempt is given attention. Heat and mass transfer analysis is examined in the frame of thermal radiation and chemical reaction. Brownian motion and thermophoresis concept is introduced due to presence of nanoparticles. Nonlinear equations of momentum, energy and concentration are transformed into dimensionless expression by invoking suitable variables. The series solutions are obtained through homotopy analysis method (HAM). Impact of embedded variables on the velocity, temperature and nanoparticles concentration is graphically presented. Numerical values of skin friction coefficient, local Nusselt and Sherwood numbers are computed and analyzed. It is concluded that velocity field enhances for fluid variable while reverse situation is noticed regarding Hartman number. Temperature and heat transfer rate behave quite reverse for Prandtl number. It is also noted that the concentration and local Sherwood number have opposite behavior in the frame of Brownian motion.
