The aim of this investigation is to study the unsteady MHD natural convective Couette flow of viscous, electrically
conducting, incompressible, Casson fluid past an infinite vertically inclined plate embedded in porous medium in the
presence of heat transfer, transverse magnetic field, hall current, viscous dissipation effects. Numerical solutions for time
dependent energy and momentum equations are obtained by an efficient, accurate and extensively validated and
unconditionally stable finite element method. The effects of various engineering parameters viz. Grashof number for heat
transfer, Magnetic field parameter, Hall parameter, Casson fluid parameter, Angle of inclination parameter, Prandtl number
and Eckert number on flow variables have been discussed numerically and explained graphically. Also, the derived
expressions for primary and secondary fluid velocities, fluid temperature, skin- friction due to primary and secondary velocity
fields, rate of heat transfer due to temperature field at the plate are obtained. Limiting case results are obtained for the non-
Newtonian fluid and compared with the literature. Physical interpretations and justifications are rendered for various results
obtained. This type of models finds applications in purification of crude oils, MHD power generators and magnetic materials
