Heat transfer experiments and pressure loss measurements have been performed for the case in which a copper porous media, Celmet[®], was inserted into an air channel flow in order to clarify its performance for enhancing convective heat transfer. The aim of this paper is to explore the effect of a flow passage, given by changing the height of the porous media attached to the lower wall, on heat transfer enhancement and pressure loss characteristics. Copper fiber layers of different height were also introduced for comparison with the results of the Celmet[®]. It was found that the given flow passage remarkably decreased the pressure drop produced by the porous media, although the ratio of the pressure drop reduction for Celmet[®] was found to be lower than that for the copper fiber layers. The ratio of maximum of the heat transfer enhancement compared to the normal channel flow was approximately 11 for the Celmet[®] block, which was approximately 1.5 times larger than that of the copper fiber block. The flow passage was found to decrease the heat transfer enhancement ratio. Since the decrease in heat transfer was small for the Celmet[®], including all of the passage cases, total performance of Celmet[®] as a heat transfer enhancing device was found to be more effective than that of the copper fiber layers.
