VELOCITY VARIATION IN MHD DOUBLE DIFFUSIVE CHEMICALLY REACTIING OF A MICROPOLAR FLUID FLOW IN A POROUS MEDIUM

摘要

This present paper reports the study of the free convection, double diffusive incompressible micropolar fluid flow between twovertical parallel plates containing a Darcy-Forchheimer porous medium. Asymmetric wall temperatures and concentrations are present andtake into account a temperature-dependent variable thermal conductivity. The similarity transformation approach is adopted to transformedsystem of non linear PDE equations to ODE which is named as linear momentum, angular momentum, energy and species. Computationalsimulation using the finite element method is done for the system of coupled differential equations. The effects of Darcy number (Da),Forchheimer number (Fs), Grashof number (Gr) and thermal conductivity parameter (S) on the velocity, angular velocity and temperature /concentration profiles are studied in detail. A comparison with another method has also been presented to show the compatibility of theproposed method.
