Research Abstract |
To Enhance boiling heat transfer, control of heating surface wettability is important because it affected bubble generation and detachment from the heating surface. In this study, the wettability of the surface from super-hydrophilic to hydrophobic can control by coating the TiO2 nanotube (TNTs) with self-assembled monolayers (SAMs) film without UV irradiation. Critical heat flux and heat transfer coefficient of pool boiling employed the surface with TNTs-SAMs film were 1.4 times and 1.5 times larger than those of normal copper surface.
