Аннотация: The impingement of a short-duration water jet on a pool of molten Rose’s metal is studiedexperimentally herein. Short-duration water jet impacting on the free surface of a molten metalpool with a temperature of 300◦C are generated with a pneumatic water delivery system, with two-camera high-speed video registration. A total of 14 experimental series, each containing 5 repeatedtests, are performed for a water volume of 0.2–1 mL and a jet impact velocity of 4.1–9.0 m/s. Thecavity development in the melt layer is studied, with the main stages described herein. Despite thesigniﬁcantly higher density of melt in comparison with water, the cavity can reach the melt poolbottom; furthermore, its further collapse results in the formation of a central jet rising to the height ofa few centimeters. The maximum height of the central jet is shown to depend linearly on the totalmomentum of the water jet, and a semi-logarithmic correlation is found for the maximum diameterof the cavity. Repeatability analysis is performed within each experimental series, and the relativestandard deviation for the melt splash height is shown to be from 8.8% to 26.8%. The effects of thepool depth, the vessel shape, and the water temperature are weaker in the range of the experimentalparameters used here.
