Effect of Variable Viscosity, Dissipation and Hall Currents on Convective Heat and Mass Transfer Flow Past a Stretching Sheet

Abstract

We consider the influence dissipation, variable viscosity, Hall current of a magneto-hydrodynamic free-convective flow and heat and mass transfer flow past a stretching sheet in the presence of heat generation/absorption. The fluid viscosity is assumed to vary as an inverse linear function of temperature. The boundary-layer equations governing the fluid flow, heat and mass transfer under consideration have been reduced to a system of non-linear ordinary differential equations by employing a similarity transformation. Using the finite difference scheme, numerical solutions to the transform ordinary differential equations have been obtained and the results are presented graphically. The rare of heat anf mass transfer sre discussed numerically for different variations.
