Heat and mass transfer analysis of carreau nanofluid over an exponentially stretching sheet in a saturated porous medium

Abstract

The present work analyses the flow of a Carreau nanofluid past an exponentially stretching sheet in a saturated porous medium, with effects of suction/injection and convective boundary condition using Buongiorno’s mathematical model. In addition, discussion has been made on the conditions of zero normal flux of nanoparticle, imposed at the surface. The governing partial differential equations of the flow, heat and nanoparticle concentration profiles were rehabilitated into a system of nonlinear ordinary differential equations by using similarity transformation. This system of equations are solved numerically by applying 4th order Runge-Kutta shooting method, and function ODE45 from MATLAB. Portrayals of flow heat and nanoparticle concentration profiles, equivalent to abundant somatic parameters are graphically as well as in tabularization form were scrutinized. © 2019 by American Scientific Publishers All rights reserved.
