Role of Initial Melt Inventory on Debris Generation With Woods Metal Water Interaction Under Drop Mode Available to Purchase

Thermal interaction of a hot liquid with a cold volatile liquid was investigated with woods metal melt water system at first contact temperature just above the spontaneous nucleation temperature of water. Drop mode experiments were carried out up to 1000 g of melt and resulting debris sizes and shapes were analyzed. Experiment was carried out with melt temperature of 425 °C and water pool at 30 °C. One of the 100 g run resulted in an energetic interaction with a mass median diameter 2.5 mm ± 1.58. The MMD is seen to change to higher values for non-energetic cases and higher melt inventories. Dynamic pressure signals are also recorded. Relative contribution of thermal and hydrodynamic fragmentation is assessed in pool and narrow geometries. Dependence of mass median diameter on initial melt inventory has been brought out.
