Abstract

The Leidenfrost effect is a phenomena manifested by a liquid droplet interacting with a surface that is considerably hotter than the boiling point of the droplet resulting in a thin vapor layer separating the droplet-surface pair. This phenomena also occurs between a droplet and a superheated immiscible liquid pair, for example a liquid nitrogen droplet in a pool of water. Due to the encapsulation of the droplet in the pool, a bubble of vapor develops around the evaporating droplet. The dynamics of the droplet evaporation and subsequent bubble growth is theoretically and experimentally investigated for a particular case of a small (capillary) droplet. The knowledge developed in this work is of interest in optimizing the cooling processes in pharma and beverage industry.
