• FINITE ELEMENT ANALYSIS OF DOUBLE-DIFFUSIVE HEAT TRANSFER FLOW IN RECTANGULAR DUCT WITH THERMO-DIFFUSION AND RADIATION EFFECTS UNDER INCLINED MAGNETIC FIELD

Abstract

An investigation has been carried out to find the influence of the thermal radiation and thermo-diffusion on convective heat and mass transfer flow of a viscous chemically reacting and electrically fluid through a porous medium in a rectangular duct under inclined magnetic field. By using Galerkin finite element method the equations governing the flow, heat and mass transfer have been solved with three nodded triangular elements. The effects of various parameters like soret parameter Sr_, chemical reaction parameter g, radiation parameter N₁, Eckert number Ec and inclination of the magnetic field the temperaturea₁, concentration C, the rate of heat and mass transfer have been depicted. It is noticed that the actual temperature and concentration reduces at the vertical levels x=1/3, 2/3 and at horizontal level y=2h/3, while reduces at the horizontal level y=h/3 with increase in radiation parameter N₁
