Comparative study on the enhancement of spray cooling heat transfer using conventional and bio-surfactants by Liu, Pengfei, Kandasamy, Ranjith, Ho, Jin Yao, Feng, Huicheng, Wong, Teck Neng

“…Meanwhile, in the nucleate boiling, spray cooling heat transfer is substantially enhanced using any of the three tested surfactants due to the decrease in surface tension and enhanced wettability. At the same concentration, the two biosurfactants lead to higher heat transfer than Tween 20 due to their lower surface tension as compared to Tween 20. …”
