ABSTRACT

The present paper deals with the heat and mass transfer of a steady free-convective laminar flow of an incompressible viscous and electrically conducting fluid over a porous flat plate in the presence of transverse magnetic field, taking into account Hall and ion slip currents. The non-linear governing equations together with the boundary conditions are reduced to a system of non-linear ordinary differential equations by using similarity transformations. The system of non-linear ordinary differential equations are solved by shooting procedure using fourth order Runge-Kutta Method. The important flow characteristics, velocity, temperature and concentration profiles as well as the skin-friction coefficient Cf, local Nusselt number Nu and the local Sherwood number Sh for various values of the non-dimensional parameters like Magnetic parameter (M), Hall current (βe), Ion-slip parameter (βi), Schmidt Number (Sc), Soret Number (Sr), Suction/Blowing parameter (S) are studied numerically.
