文摘

The temperature distributions increase along with increases in the flow direction axis. The presence of an aluminum foam filled channel enhanced the heat transfer by 20%. The highest Nusselt number is achieved at a γ-Al2O3 particle loading of 0.2 vol%. The enhancement of 0.2 vol% nanofluid were 37% and 28% over the range of Reynolds numbers. Empirical correlations of Nusselt number were developed based on the experimental data.
