Mixed Convection Heat Transfer

The magnetohydrodynamics-mixed convection heat transfer problem from a vertical surface embedded in a porous media is studied. The effects of transverse magnetic field and radiation heat transfer are examined. Both cases of the mixed convection heat transfer problem, namely: the buoyancy aiding flow and the buoyancy opposing flow are investigated. It is found that three dimensionless groups can describe the problem under consideration, the mixed convection parameter ζ, the radiation-conduction parameter Rd, and the magnetic field number Hax2∕Rex. Different velocity profiles, temperature profiles, and the local Nusselt number variations are also drawn.
