“…at TN) corresponds usually to a range of temperature, which may extent up to 20K. In addition, the experimental results have shown the high variation of the Nukiyama temperature with the wall materials [9,10]. Besides, among the many mechanisms important to spray cooling, Leidenfrost point (LFP) represents a crucial transition point having appreciable impact on wall cooling by the fuel spray impingement, particularly in internal combustion engines, as discussed in [6], for instance.…”

“…(1) Plasma irradiation (2) Surface roughness (3) Super-water-repellent coating First, we explain the effect of plasma irradiation [2] on surface wettability. When the surface of metal is irradiated by plasma, the gas adsorption layer formed by adsorption of inert gas in the atmosphere is removed instantly and a surface with higher activity is revealed.…”

The effect of surface wettability on evaporation of a water drop has been examined experimentally using surfaces with various contact angles. To greatly change the surface wettability, TiO 2 superhydrophilicity, plasma irradiation, and super-water-repellent 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 was obtained and it was found that the lifetime of a water drop dramatically decreases with contact angle in the lower temperature region, and that the wetting limit temperature increases with the contact angle.
