Integral solution for hydromagnetic mixed convection heat and mass transfer from a vertical surface in a saturated porous medium

This work studies the coupled heat and mass transfer by mixed convection from vertical plates with constant wall temperature and concentration in a porous medium saturated with an electrically conducting fluid in the presence of a transverse magnetic field. The integral method is applied to obtain the solution. The effects of the buoyancy ratio, the Lewis number, the buoyancy parameter, and the magnetic parameter on the local Nusselt number, the local Sherwood number, and the ratio of the thermal boundary layer thickness to the concentration boundary layer thickness are studied. An increase in the buoyancy parameter tends to increase the local Nusselt number and the local Sherwood number. However, increasing the magnetic parameter decreases the local Nusselt number and the local Sherwood number.
