... preheating temperature ratio, Reynolds number and medium porosity on local and average heat transfer behavior of porous aluminum-foam heat sinks in a channel are explored. The heat transfer enhancement of using a porous heat sink in a channel to a hollow channel is, ( N u ¯ b ) s s ∕ ( N u ¯ b ) ε = 1 , much...

... correlations of thermal resistance in terms of air mass flow rate with a power of − 0.228 are presented. As for average Nusselt number, the effect of chip heat flux on the average Nusselt number is insignificant; while the average Nusselt number of the cold plate increases with increasing Reynolds number...
