MHD Flow and Heat Transfer for Second Grade Fluid in a Porous Medium with Modified Darcy's Law

In this work, an unsteady unidirectional second grade fluid in a porous medium is considered. A modified Darcy's law is introduced to study the unsteady problem. A strong magnetic field is applied, which acts perpendicular to the velocity field. Slip is considered between the plate and the fluid. Finally, the heat transfer analysis with regard to the modified Darcy's law is discussed.
