HEAT TRANSFER IN POROUS MEDIA: A REVIEW

Abstract

Heat-transfer through porous media takes advantage of the fact that governing equations used for describing various flow and transport phenomena in porous media are all generally based on the same form of mass and/or energy conservation laws. The local distributions of the Nusselt number along the flow direction increase with the increase of the Reynolds number and thickness of the porous layer, but increase with the decreasing Darcy number. The wall temperature and concentration are constant and the medium is linearly stratified in the vertical direction with respect to the thermal conditions. When the fluid flows through porous media, pressure difference reduces with increasing porous parameter which implies a reduction in mass of the fluid that reduces the velocities of the fluid and the dust particles. The simulation model can predict the transient development of sheet temperature very accurately under the specified heating conditions. The theory of porous media for heat transfer in biological tissues is found to be most appropriate since it contains fewer assumptions as compared to different bioheat models.
