Abstract

Abstract

Based on the SIMPLE scheme on structured/unstructured collocated meshes,the code used for the prediction of the flow and heat transfer characteristics in porous media domain was achieved,where the momentum equations are formulated by Darcy-Brinkman-Forchheimer model;and the thermal equilibrium model is adopted for energy equation.The heat transfer characteristics of parallel-plate channel with porous inserts along the channel center and wall region were analyzed respectively.The results indicate that compared with the clear channel,the porous inserts can enhance the heat transfer,but cause large pressure drop as well.The performance has a great relationship with the porous media insert modes and filling ratio.Under the conditions of this paper,at low Re number,the channel with porous insert along the wall region has better comprehensive heat transfer performance.
