MHD Heat and Mass Transfer Forced Convection Flow Along a Stretching Sheet with Heat Generation, Radiation and Viscous Dissipation

Abstract

The present study comprises of steady two dimensional magnetohydrodynamic heat and mass transfer forced convection flow along a
vertical stretching sheet in the presence of magnetic field with radiation and viscous dissipation. The problem has been analyzed by
applying Nachtsheim-Swigert shooting iteration technique with sixth order Runge-Kutta integration scheme. The nonlinear partial
differential equations governing the flow field occurring in the problem have been transformed to dimensionless nonlinear ordinary
differential equations by introducing suitably selected similarity variables. The ensuing equations are simultaneously solved by applying
numerical iteration scheme for velocity, temperature and concentration fields. The results are displayed graphically in the form of velocity,
temperature and concentration profiles. The corresponding skin-friction coefficient, Nusselt number and Sherwood number are displayed in
tabular form. Several important parameters such as the Prandtl number (Pr), radiation parameter (N), magnetic field parameter (M), heat
source parameter (Q), Schmidt number (Sc), suction parameter (fw) and Eckert number (Ec) are confronted. The effects of these parameters
on the velocity, temperature and concentration profiles are investigated.
