Nucleate pool boiling is a mode of pool boiling that tends to transfer heat more efficiently than the other modes of pool boiling. Many studies have been done to augment the heat transferred during nucleate pool boiling. Various methods of heat transfer augmentation in

boiling can be performed through active treatments (mechanical aids, surface/fluid vibrations, etc.) or passive treatments (functional coating, surface roughening, etc.). This study focuses primarily on a passive treatment, specifically TiO2 coating, which involves testing a substrate coated with TiO2 using NeverWetTM base coating as a coupling agent and coated using a method outlined by Wu et …
