Finite Element Results of Unsteady free convection flow Past a Vertical Permeable Moving Plate in Presence of Magnetic Field, Heat and Mass Transfer Effects

Abstract

The problem of unsteady boundary layer flow of a viscous, incompressible, electrically conducting fluid along a semi-infinite vertical permeable moving plate in the presence of a uniform transverse magnetic field, heat and mass transfer effects are considered. The plate is assumed to move with a constant velocity in the direction of fluid flow while the free stream velocity is assumed to follow the exponentially increasing and time-dependent wall suction is assumed to occur at the permeable surface. The dimensionless governing equations for this investigation are solved numerically using finite element method. The evaluation of the numerical results is performed and some graphical results for the velocity, temperature and concentration profiles within the boundary layer and tabulated results for the skin-friction coefficient, Nusselt and the Sherwood numbers are presented and discussed.
