Soret effect on entropy generation at magneto double-diffusive convection in an air filled square medium

In the present approach, entropy generation at a two-dimensional steady MHD natural convection flow and mass transfer in a square confined cavity filled with a binary fluid has been analyzed numerically including the Soret and the magnetic effects. Dirichlet boundary conditions for temperature and solute concentration are applied to the two vertical walls of the enclosure; whereas the two horizontal walls are adiabatic and insulated. The governing differential equations of the problem have been solved numerically using a Control Volume Fined Elements Method, CVFEM of Patankar. The total entropy generation rate, dimensionless velocity and concentration profiles are displayed graphically showing the effects for the different values of the involved parameters of the problem. Moreover, the effects of Soret parameter, Thermal Grashof number, Hartmann number and buoyancy ratio are shown. The investigated results showed that the flow field and then entropy generation are notably influenced by the considering parameters.
