Steady mixed convective magnetohydrodynamic mass transfer flow with induced magnetic field and heat generation effects

The study of steady heat and mass transfer by mixed convection flow from a vertical porous plate with heat generation has been made under the action of transverse magnetic field taking into account the induced magnetic field with viscous and magnetic dissipations of energy. The porous plate is subjected to a constant suction velocity as well as a uniform free stream velocity. The boundary layer equations have been transformed into dimensionless coupled nonlinear ordinary differential equations by appropriate transformations. The similarity solutions of the transformed dimensionless equations for the flow field, induced magnetic field, current density, heat and mass transfer characteristics are obtained by series solution technique and their numerical results' are presented in the form of graphs. The results show that heat generation decreases the fluid velocity when free convection currents cool the plate. The x-component of induced magnetic field is significantly affected by the magnetic field, magnetic Prandtl number and heat generation parameter. Applications of the study include laminar magneto-aerodynamics, materials processing and MHD propulsion thermo-fluid dynamics. (author)
