Abstract
In this paper the steady laminar magneto hydrodynamic (MHD) mixed convection boundary layer flow towards a vertical stretching sheet with variable
fluid viscosity, radiation and in the presence of Dufour’s effect have been investigated. The governing partial differential equations are transformed
into set of ordinary differential equations using similarity transformation, and then these equations have been solved numerically using Runge- Kutta
method with shooting technique. Results shows that magnitude of skin friction coefficient decreases, while magnitude of heat transfer coefficient and
mass transfer coefficient increases with decreasing values of viscosity variation parameter for the case of opposing flow. But in the case of assisting
flow magnitude of skin friction coefficient, heat transfer coefficient and mass transfer coefficient decreases with decreasing values of viscosity
parameter. Also magnitude of skin friction coefficient and heat transfer coefficient decreases with increasing values of Dufour number for both assisting
and opposing flow, and there is a slight change in magnitude of mass transfer coefficient with Dufour number. Magnitude of velocity increases with
increasing values of Dufour number for both assisting and opposing flow.
