Computational unsteady forced convection over a stretching sheet with magnetic and radiative physical effects to the fluid flow field

A heat transfer for steady two-dimensional forced convection with magnetic hydrodynamic flow (MHD) with radiative effect of an incompressible fluid over an unsteady thermal forming stretching sheet has been studied. The parameters M and R which are used to represent the dominance of the magnetic effect and radiative effect have been presented in governing equations. The similar transformation and an implicit finite-difference method have been used to analyze the present problem. The numerical solutions of the flow velocity distributions, temperature profiles, the wall unknown values of f′(0) and θ ′(0) for calculating the heat transfer of the similar boundary-layer flow are carried out as functions of the unsteadiness parameter (S), the Prandtl number (Pr), the radiative parameter (R) and the magnetic parameter (M). The effects of these parameters have also discussed. At the results, it will produce greater heat transfer effect with a larger Pr, R and S but a larger M will reduce momentum and heat transfer effects.
