A numerical study is made of heat transfer characteristics from pulsating flow in a concentric annutus partially filled with porous media. The unsteady Navier-Stokes equations with the Brinkman-Forchheimer-extended Darcy model in the porous region art solved by using finite volume techniques. Changes in connective heat transfer and in effective anal heat conduction due to pulsation are investigated over broad ranges of the relevant parameters, i.e., the thickness of the porous layer and the frequency and amplitude of pulsation. The results obtained indicate that the effective axial thermal conductivity is substantially increased by pulsation, and this augmentation is more pronounced by partial fillings of porous material
