Thermo-Diffusion and Chemical Reaction Effects on a Steady Mixed Convective Heat and Mass Transfer Flow with Induced Magnetic Field

This paper is focuses on the effects of soret and chemical reaction on a two dimensional, laminar, mixed convective heat and mass transfer flow of a viscous incompressible electrically conducting and radiating fluid over a vertical porous plate in the presence of a transverse applied magnetic field and constant suction, by taking induced magnetic field into account. The boundary layer equations have been transformed into dimensionless coupled nonlinear ordinary differential equations by similarity transformations. The resultant dimensionless governing equations are solved by series solution technique. The influences of various thermo physical parameters on the velocity, temperature, concentration and induced magnetic fields are discussed. It is observed that the induced magnetic field increases with a rise in chemical reaction parameter or Hartmann number or radiation parameter or Schmidt number, whereas it decreases with an increase in the soret number. This model finds applications in laminar magneto-aero dynamics, material process and MHD propulsion thermo fluid dynamics
