| Outline of Final Research Achievements |
Clear understanding of mechanism and effect of surface condition on droplet evaporation is indispensable for the development of innovative rapid cooling technique. The present study consists of two parts; (1) measurement of temperature and heat flux distributions of liquid-solid interface by means of high-speed infrared camera, and (2) pseudo-spray cooling by means of micro-jet dispenser with stainless samples with different surface treatment and with different impact angles. Observation by high-speed camera revealed that impacting angle of the drop, one of the key parameters, influences the cooling rate. During collision of droplet with hot surface, the drop moves along the surface before taking-off and the relation of moving length with cooling rate was obtained.
