| Abstract: | In order to study the mechanism of steam explosion caused by the interactionbetween coolant and melted metal drops with high temperature, the process of explosion generated by water following interaction with molten metal drops is carried out. In the experiment,liquid aluminum and water with different ratios and different temperatures were evaluated, and the influence of different water temperatures on the steam explosion was studied. The corresponding rules of steam explosion at the different experimental conditions were derived. The difference between experiment resultants was analyzed. The experimental results show that when the ratios of liquid aluminum to water are within a certain range, explosions maybe happen, and the higher the temperature of water is, the less likely explosions will occur while other conditions remain the same. The research results would provide an insight into controlling steam explosion. |
