Numerical study of unsteady free convective heat transfer in Walters-B viscoelastic flow over an inclined stretching sheet with heat source and magnetic field

Abstract

An investigation was carried out on the numerical study of unsteady free convective heat transfer in Walters-B viscoelastic flow over an inclined stretching sheet with heat source and magnetic field. The dimensionless governing equations are solved using an implicit finite difference method of Crank-Nicolson type. The effects of various parameters on the velocity and temperature fields as well as the coefficient of skin-friction and Nusselt number were presented graphically and in tabulated forms. It is observed that, when the heat source parameter increases, the velocity and temperature increase in the boundary layer.
