MHD double diffusive mixed convective boundary layer flow of nanofluid past a linear stretching vertical plate

Abstract

In the present work the time independent two-dimensional laminar double diffusive boundary layer flow of MHD nanofluid over a linear stretching plate is studied numerically. The effect of Dofour effect, Soret effect, Brownian motion and thermophoresis is considered in the transport model formed. The nanoparticles flux at the surface of the plate is taken as zero. Initially the similarity transformation is applied to convert the equations into non-dimensional form and then transformed equations are solved using Frehdlom-Runge Kutta fourth fifth order method. The effect of magnetic field parameter, Prandtl number and Buoyancy force owed by temperature difference on dimensionless velocity, temperature profile, dimensionless solute concentration and dimensionless nanoparticles volume fraction is illustrated graphically. A linear correlation has also been established for reduced Nusselt number which involves the effects of various parameters.
