Abstract

The using of the high-speed (not less than 105 frames per second) video recording tools (Phantom) and the software package (TEMA Automotive) allowed carrying out an experimental research of laws of intensive vaporization with an explosive disintegration of heterogeneous (with a single solid non-transparent inclusion) liquid droplet (by the example of water) in high-temperature (500-800 K) gases (combustion products). Times of the processes under consideration and stages (liquid heat-up, evaporation from an external surface, bubble boiling at internal interfaces, growth of bubble sizes, explosive droplet breakup) were established. Necessary conditions of an explosive vaporization of a heterogeneous droplet were found out. Mechanisms of this process and an influence of properties of liquid and inclusion material on them were determined.
