Abstract:

        Aim of the paper is to investigate an unsteady magnetohydrodynamic free convection fluid flow through a porous medium with oscillating temperature here, taking into account of the homogeneous chemical reaction of first order. The dimensionless governing equations are solved numerically by using finite element technique. The effects of the various physical parameters on the velocity, temperature and concentration are discussed numerically and presented through graphs and Tables. The skin-friction coefficient, the Nusselt number and the Sherwood number at the plate are discussed and their numerical values for various values of physical parameters are presented through tables.

Key words: chemical reaction, MHD, oscillating temperature, finite element method.
