Abstract

Effect of surface wettability on evaporation of water drop has been examined experimentaly using surfaces with various contact angles. To change widely the surface wettability, TiO2 superhydrophilicity, plasma irradiation and super-wate-reppllent surface are adopted as the heating surface. The range in contact angle achieved by these methods was between 0° and 170°. The relationship between the contact angle and the wetting limit temperature were obtained and it was found that the lifetime of water drop dramatically decreases with contact angle in lower temperature region, and that the wetting limit temperature increases with contact angle.
