Abstract—The laminar field and heat transfer enhancement of forced convection in various counter flow porous channels with a joint aluminum plate was studied, using control volume technique and SIMPLE procedure for the velocity-pressure Coupling. Hydrodynamic and heat transfer results are reported for three configurations: (1) nonporous channels (NPC) (2) both channels filled by porous structure (BPC), and (3) only the channel contains hot fluid, filled by porous structure and other one is nonporous (HPC). The effectiveness, pressure drop and temperature difference are evaluated for wide ranges of Darcy, Reynolds and Prandtl numbers, also effects of thermal conductivity ratio is considered. The results show that as the Darcy, Reynolds or Prandtl number decreases, an increase in effectiveness is obtained. Also increase of thermal conductivity ratio causes to different effects on effectiveness in each case.
