Outline of Final Research Achievements |
Rewetting on a hot surface is an essential phenomenon governing inception of rapid cooling during transient cooling with boiling heat transfer. This study was conducted to elucidate rewetting phenomena during spray quenching. An experimental apparatus to evaluate fundamental transition boiling phenomena simulated with boiling of single or multiple sessile droplets on a hot nickel surface. High speed video imaging technology and fast response surface temperature measurement techniques were applied. As a governing parameter of the wetting phenomena, vapor generation time delay after sudden contact of liquid and solid surface was characterized.
