Abstract
The present work investigates heat transfer in different configurations of pipes filled with porous media under local thermal non-equilibrium condition. Two configurations consider the pipe partially filled with porous media, a pipe with a porous layer inserted at the wall and a pipe with a porous media at the core. A third configuration is a pipe completely filled with porous media. The flow is assumed to be laminar. The pressure drop, fluid and solid temperature distributions are calculated. The local Nusselt number of the different configurations is presented. The effect of the porosity on the different configurations is analysed. The configuration of the tube with a porous layer on the wall presented a low heat transfer efficiency. The tubes filled with porous media in the core region presented a good heat transfer efficiency and a low pressure drop.
