Inspection of Coriolis and Lorentz forces in nanomaterial flow of non-Newtonian fluid with activation energy

The main purpose of this article is to investigate the flow of third grade nanofluid due to rotating stretchable disk. Moreover, the effects of magnetohydrodynamic, nonlinear thermal radiation, Joule heating, activation energy, thermophoresis and Brownian movement are also accounted. By appropriate transformation transformed the governing PDE's into ODE's. The arising ODE's are solved analytically by means of homotopy analysis method. The effects of different flow variables on temperature, velocities, concentration, skin frictions, Nusselt and Sherwood numbers are captured and analyzed graphically. The obtained results show that velocity is a decreasing function of material parameters as well as Hartmann number (magnetic parameter). Temperature increased with Brownian motion variables, thermal radiation parameter and thermophoresis parameter. Concentration reduced through chemical reaction and Schmidt number while enhanced with thermophoresis parameter, fitted rate constant and activation energy. (C) 2019 Elsevier B.V. All rights reserved.
