Effects of non-uniform wall temperature or mass transfer in finite sections of an inclined plate on the MHD natural convection flow in a temperature stratified high-porosity medium

MHD Natural convection from a non-isothermal inclined surface with multiple suction/injection slots embedded in a thermally stratified high-porosity medium has been studied. The non-linear coupled parabolic partial differential equations have been solved numerically by using an implicit finite-difference scheme. The non-uniform wall temperature or the surface mass transfer in finite sections of the surface strongly affect the heat transfer and the skin friction. When the surface in the slots is cooled, the direction of the heat transfer changes. Both the skin friction and the heat transfer increase due to suction but decrease due to injection. The heat transfer, in general, changes significantly with the stratification and magnetic parameters, in the slot near the trailing edge of the plate
