Thermal interaction of high-temperature melts with liquids

A review of experimental and computational-theoretical works devoted to the study of the interaction of high-temperature melts with liquids, which can lead to the release of mechanical energy (steam explosions), being a potential hazard for industrial facilities, primarily for nuclear power plants, is carried out. Both large-scale steam explosions involving tens of kilograms of melts and small-scale interactions of individual melt drops with liquid coolants are considered. The importance of the regime of unstable film boiling for determining the conditions for the initiation of a steam explosion is noted. Studies of the influence of the solidification of the melt surface on the thermal interaction of the melt with the coolant are analyzed. The role of melt-oxidation processes in the development of a steam explosion is shown.
