• INFLUENCE OF HALL CURRENT ON AN UNSTEADY FREE CONVECTIVE FLUID FLOW ALONG A FLAT PLATE SURROUNDED BY POROUS MEDIUM IN THE PRESENCE OF MAGNETIC FIELD AND VISCOUS DISSIPATION

Abstract

The aim of this research work is to study the effect of Hall current on an unsteady magnetohydrodynamic flow of an electrically conducting incompressible fluid flow along an infinite vertical porous flat plate in presence of viscous dissipation and  heat absorption. The problem is governed by the non-linear coupled partial differential equations and are solved, numerically by finite element method for velocity, temperature, concentration fields and also the expressions for shearing stress, rate of heat transfer and mass transfer are derived and discussed. The effects of Grashof Number, Modified Grashof Number, Transpiration cooling parameter, Prandtl Number, Schmidt Number, Eckert number, Hartmann number and Hall parameter on the flow field are shown through graphs and tables.
