Description
Summary:In this article, the steady MHD Nanofluid flow with heat and mass transfer is investigated numerically for Williamson non-Newtonian fluids with variable thermo-physical properties, under the combined effects of thermal, velocity slip and uniform transverse magnetic, in the case where the flow is established semi-infinite vertical plate. The governing differential equations of the present problem are obtained by considering the Buongiorno's mathematical model, which takes into account the Brownian motion and thermophoresis effects. The non-dimensional, transformed boundary layer equations for momentum and energy are solved with the second order accurate implicit Keller box finite difference method under appropriate boundary conditions. The effects of major parameters on the dimensionless velocity, temperature and nanoparticle volume fraction are analyzed numerically via representative profiles of these variables, whereas the skin friction factor and the heat transfer rate are estimated numerically and their effective values are tabulated for different controlling parameters.
