- Abstract
Focuses on Titanium Dioxide (TiO2), which is a photocatalyst with a unique characteristic. How a surface coated with TiO2 exhibits an extremely high affinity for water when exposed to ultraviolet (UV) light and the contact angle decreases nearly to zero; Experiment involving the pool boiling of pure water has been performed to make clear the effect of high wettability on heat transfer characteristics; How the heat transfer surface is a vertical copper cylinder and the measurement has been done at saturated temperature and in a steady state; Comparison of both TiO2-coated and non-coated surfaces; Findings when the TiO2-coated surface is exposed to UV light for a few hours before experiment; Temperature at minimum heat flux (MHF) for the superhydrophilic surface; View that the superhydrophilic surface can be an ideal heat transfer surface.
