### HEAT AND MASS TRANSFER EFFECTS ON AN UNSTEADY HYDROMAGNETIC FREE CONVECTIVE FLOW OVER AN INFINITE VERTICAL PLATE EMBEDDED IN A POROUS MEDIUM WITH HEAT ABSORPTION

#### Abstract

An unsteady, two dimensional, hydro magnetic, laminar mixed convective boundary layer flow of an incompressible and electrically conducting fluid along an infinite vertical plate embedded in the porous medium with heat and mass transfer is analyzed, by taking into account the effects of viscous dissipation and heat absorption. The dimensionless governing equations for this investigation are solved analytically using Galerkin finite element method. Numerical evaluation of the numerical results is performed and the results for velocity, temperature and concentration profiles within the boundary layer are discussed and shown through graphically.
