THERMAL INTERACTION OF LEAD-ALLOY DROPLET WITH SUBCOOLED WATER IN POOL WATER TANK
Visualization test was conducted by designing and setting up a special experimental apparatus to investigate characteristics of thermal-hydraulic interaction between lead-alloy droplet and subcooled water in pool water tank. The violent boiling phenomena were observed by a high-speed camera and local transient pressure was measured by high frequency piezo pressure transducer. The results showed that violent boiling mainly occurred when interface temperature between droplet and water was higher than homogenous nucleation temperature of water and subcooling temperature of water was higher than 40K. A violent boiling model for lead-alloy droplet/water interaction was proposed. In the model, partial contact of lead-alloy droplet with water caused by vapor film instability was taken into account to simulate fragmentation due to rapid evaporation.
