Magnetohydrodynamic Flow of a Non-Newtonian Nanofluid Over an Impermeable Surface with Heat Generation/Absorption

An analysis has been carried out to study the magnetohydrodynamic boundary layer flow and heat transfer characteristics of a non-Newtonian nanofluid over a flat sheet in the presence of heat generation/absorption. The governing nonlinear partial differential equations are transformed into a system of coupled nonlinear ordinary differential equations using similarity transformations and then tackled numerically using the Runge-Kutta-Fehlberg-45 method. The velocity, temperature and nanoparticle concentration profiles are analyzed with respect to the involved parameters, namely, Prandtl number Pr, magnetic parameter M, source/sink parame-ter A, Brownian motion parameter Nb, thermophoresis parameter Nt and Lewis number Le. It is found that the temperature of the fluid increases with the increase in heat source parameter and decreases with heat sink parameter.
