摘要：

In this paper, force convection heat transfer of a porous medium in a laminar channel flow is numerically investigated. The porous medium with random porosities is used to enhance heat transfer and the random porosities are derived by the Kinderman-Ramage procedure. The results show that when the mean porosity is larger than 0.5, the average Nusselt numbers are enhanced and better than the solid block case. Therefore, a porous medium with larger porosity and the proper bead diameter could provide more heat dissipation. For the random porosity distribution, the profiles of velocities are disordered and the channeling effect is not apparent near the plate region.
