Magnetohydrodynamic flow and mixed convection of a viscous fluid and a nanofluid through a porous medium in a vertical channel

This paper analyzes the MHD flow and heat transfer of a pure fluid nanofluid through porous medium in vertical channel. The right half channel contains left nanofluid, which is immiscible with half. Channel walls are impermeable at constant temperatures. An external homogeneous magnetic field perpendicular to applied on Darcian approach used model medium. Relevant differential equations solved using perturbation method. Velocity temperature distributions determined analytically represented graphically, while values skin friction Nusselt number given table for multiple introduced physical parameters. results draw conclusions about influence said parameters velocity walls.
