Mixed convection flow over a vertical wedge embedded in a highly porous medium

The steady mixed convection flow over a vertical wedge with a magnetic fiel d embedded in a porous medium has been investigated. The effects of the per meability of the medium, surface mass transfer and viscous dissipation on t he flow and temperature fields have been included in the analysis. The coup led nonlinear partial differential equations governing the flow field have been solved numerically using the Keller box method. The skin friction and heat transfer are found to increase with the parameters characterizing the permeability of the medium, buoyancy force, magnetic field and pressure gra dient. However the effect of the permeability and magnetic field on the hea t transfer is very small. The heat transfer increases with the Prandtl numb er, but the skin friction decreases. The buoyancy force which assists the f orced convection flow causes an overshoot in the velocity profiles. Both th e skin friction and heat transfer increase with suction and the effect of i njection is just the reverse.
