FEM AND FDM CORRELATIVE STUDY ON UNSTEADY FLOW PAST A POROUS PLATE IN THE PRESENCE OF MAGNETIC FIELD

In this study, the effects of Soret, Dufour, and Hall currents on free-convection flow of incompressible viscous fluid along vertical porous plat plate subjected to a time-dependent transpiration velocity and chemical reaction are analysed using a comparison of finite difference (FDM) and finite element method (FEM). A magnetic field is applied to the flow in the normal direction. Finite difference and Galerkin finite element methods are used to solve governing coupled non linear differential equations. To understand the effects of various parameters on flow pattern, a parametric research is conducted. The graphical results achieved through the use of finite element and finite difference approaches are shown and compared. The Galerkin finite element method was shown to be more efficient in comparison. The acquired results are in good agreement with physical phenomena that occur in actual life.
