Abstract
In this study, the heat transfer characteristics of Al2O3–water nanofluid were investigated experimentally in a rectangular natural circulation loop of 402mm in height and 205mm in width. The 120-mm-long heated section and 155-mm-long cooling section in the loop were constructed with mini-channel heat exchangers. The nanometer-sized particles of alumina (Al2O3) were dispersed in pure water (the base fluid) to form the alumina–water nanofluid with mass fractions in the range of 0.1–1wt.%. The results clearly indicate that Al2O3–water nanofluid can markedly enhance the heat-transfer performance of the natural circulation loop considered. The average heat-transfer effectiveness at the heating and cooling sections were approximately 3.5–22% and 9.5–62% respectively.
