AB - 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 nontransparent 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.
