摘要: Abstract In this study, the heat transfer characteristics of an aluminum foam sink subject to impinging air jet is investigated experimentally, under fixed pumping power condition. The effects dimensionless power, Reynolds number and distance on Nusselt are considered. result shows that effect negligible number, while decreases with decreasing power. Based experimental results, empirical correlation for predicting suggested as a function distance. shown have better thermal performance than pin fin same porosity impingement cooling, when low. trend reversed larger number. cross sectional shape be insignificant.
