Résumé

This work presents an algorithm model for estimating the heat transfer by forced convection of the porous heat sink in a channel by applying the fin theory and the concept of the thermal network. The proposed algorithm model is simpler and more convenient than numerical analysis. By comparison with numerical calculations and other experiments, the model was verified to predict accurately heat transfer in various porous channels, such as metal foam channels and sintered porous channels. The inlet thermal boundary condition is also examined. [Reprinted with permission from Elsevier. Copyright, 2005].
