Hall Current and Viscous Dissipation Effects on Boundary Layer Flow of Heat Transfer Past a Stretching Sheet

Abstract

The effect of Hall current and viscous dissipation on MHD natural convective heat transfer flow of a compressible viscous fluid past a stretching surface in the presence of strong magnetic field has been considered in the present work. A magnetic field is applied transversely to the direction of the flow. By means of similarity transformation the governing equations are transformed into nonlinear ordinary flow and heat transfer characteristics which are evaluated by making the use of Nachtsheim–Swigert iteration technique along with the sixth order Runge–Kutta integration scheme. Validation is achieved through the use of Mathematica software as well. The influence of various parameters is then presented graphically in the form of non-dimensional velocity (primary and secondary) and temperature within the boundary layer entering into the problem. Also the effects of the pertinent parameters on the skin-friction coefficients and rate of heat transfer in terms of the Nusselt number, which are of physical interest, are sorted out and presented in the form of table and the conclusion is drawn that the flow field and other quantities of physical interest are significantly influenced by these parameters.
