Abstract

The phenomenon of water boiling at a phase interface inside an inhomogeneous (containing a carbonaceous particle) water droplet heated in a high-temperature (above 650 K) gaseous medium has been studied by high-speed (up to 105 fps) video recording. Characteristic stages of intense evaporation from the external boundary, bubble formation on the particle surface, explosive vaporization at the phase interface inside the droplet, and disintegration of the droplet have been recognized.
