Enhancement of forced-convection cooling of multiple heated blocks in a channel using porous covers

Fluid flow and heat transfer characteristics of the porous metallic heat sink with a conductive cylinder partially filled in a rectangular channel

“…The baffles or fins were used as the conductive pipes to enhance the thermal performance of the heat sink by increasing the heating area. Rizk and Kleinstreuer [12], Ould-Amer et al [13] and Huang et al [14] numerically studied the enhancement of forced convection cooling of discrete heated blocks in a channel using porous media. They found that the efficiency of the new configuration was around 50% higher than that of a traditional open-channel cooling system.…”

Large-eddy simulations (LES) of temperature fluctuations in a mixing tee with/without a porous medium

“…The designers then seek to reduce the temperature fluctuations to improve the structural integrity. There have been many theoretical and numerical investigations [14][15][16][17][18][19][20][21][22][23][24][25] of fluid flow and heat transfer in channels fully or partially packed with porous media in recent years due to the interest in a wide range of engineering applications such as heat exchangers, heat pipes, electronic cooling, thermal insulation, geothermal energy systems, enhanced oil recovery, and drying. The porous material improves the convective heat transfer due to the high surface area to volume ratio in the system and the enhanced flow mixing caused by the tortuous path through the porous matrix which improves the thermal dispersion.…”

Analysis of pulsating convection from two heat sources mounted with porous blocks

“…However, the result is opposite for H Ã p ¼ 1. Huang et al [10] analyzed forced convective heat transfer from multiple heated blocks in a channel by porous covers and found that the recirculation caused by porous-covering block will significantly augment the heat transfer rate on both top and right faces of second and subsequent blocks.…”
