抄録

An experimental and theoretical study of Leidenfrost film boiling when a volatile liquid droplet is released onto a hot liquid surface is presented. Photographic studies are first made with respect to the evaporation configurations. The evaporation-time curve for a variety of liquid-liquid combinations is measured and the Leidenfrost temperature is proved to be correlated by the interface temperature and the superheat limit of the volatile liquid. A heat- and mass-transfer model of liquid-liquid Leidenfrost film boiling is proposed and formulated theoretically. The calculated results of the theory are compared with the experimental radius-time data, where the radius decreases linearly with the lapse of time, except for the final stage of evaporation, and a good agreement between them is obtained. Further, the effects of physical properties are evaluted on the basis of the theoretical calculations.
