The convective motion of two incompressible viscous fluids that are different in thermal conductivities, viscosities and densities with heat transfer aspects in a rotating inclined channel, in which the pressure gradient is kept constant, is studied. The two phases are occupied by two different homogeneous isotropic porous materials having different permeabilities. The flow is steady, laminar and fully developed. Due to the inclusion of buoyancy forces, viscous and Darcy dissipation terms, the governing equations are non-linear and coupled. The regular Perturbation Method is used to obtain their solutions. The effects of the governing parameters such as rotation parameter, porous parameter, angle of inclination, Grashof number, ratio of heights, the ratio of viscosities and the ratio of thermal conductivities on the fluid flow are discussed in detail. It is observed that an increase in the Coriolis force incorporated through rotation parameter reduces the temperature and primary velocity of the flow.
