This paper deals with non-Darcian convective hydromagnetic flow in an inclined composite porous medium. It is assumed that the flow is steady, laminar fully developed and that fluid properties are constant. The flow in both phases is assumed to be driven by a common constant pressure gradient   and temperature gradient   where T_W1 and T_W2 are the temperatures of upper and lower plates. It is also assumed that at any given instant, the temperatures of fluid and the solid are the same. The viscous and Darcy dissipation terms and included in the energy equation. The governing equation is coupled and non-linear because of inclusion of dissipation terms and buoyancy force. The equations are solved using perturbation method. The effects of various parameters such as Hartmann number, porous parameter, inclination angle and Grashoff number on the flow quantities are discussed.

Keywords: Hydromagnetic flow, Darcy dissipation, buoyancy force, Hartmann number.
