The most important thermal-hydraulic parameter in heat transfer system design and safety analysis is Critical Heat Flux (CHF). Many research have been conducted to investigate CHF enhancement technique such as by surface roughening, surface coating, by adding soluble addictive, and by adding nanofluids. Nanofluids have been attracting significant attention since it found be able give a significant CHF enhancement. This article summarizes the recent research in experimental study on CHF enhancement at Pool boiling and Flow boiling conditions using nanofluids, and identifies the challenges and opportunities for future research.
