Soret effect, Dufour effect, viscous dissipation, chemical reaction, Micropolar fluid


The present paper deals with the study of micropolar fluid flow of an unsteady incompressible free convection heat and mass transfer flow past a semi-infinite vertical plate fixed firmly in porous medium with the influence of heat absorption, viscous dissipation, Soret, Dufour and chemical reaction has been analyzed. The governing partial differential equations are transformed into a set of coupled partial differential equations using suitable dimensionless quantities. The resulting non-dimensional boundary value problem is solved by the Galerkin finite element method. The effects of different pertinent parameters on translation velocity, microrotation, temperature and concentration distributions along boundary layer have been represented with the help of graphs. Under special case, comparison of the Skin friction, Wall couple stress, Nusselt number and Sherwood number are made with the Numerical results available from the literature obtained through analytical approach and found to be in good agreement.
