| 为探究高温熔融铝液与水相互作用的爆炸机理，设计了一套高温熔融铝液与水接触爆炸实验测试系统，应用红外热像仪、高速摄像机、压力传感器等设备监测高温熔融铝液与水相互作用过程，并对高温熔融铝液与水接触爆炸过程的能量转化规律进行了分析。实验结果表明：高温熔融铝液与水接触瞬间发生膜态沸腾，水剧烈汽化产生的冲击在水中产生扰动并快速扩张，40ms后膜态沸腾向核态沸腾转变，直至发生爆炸喷溅。综合能量守恒定律、爆炸冲击理论与实验结果可得，高温熔融铝液与水接触爆炸过程，约有3.34%~11.23%高温熔融铝液的潜热能转化为爆炸冲击波能量。 |
| 英文摘要: |
| In order to explore the mechanism of interaction between high temperature molten aluminum and water, a set of high temperature molten aluminum liquid and water contact explosion experimental test system was designed. The process of interaction between high temperature molten aluminum liquid and water was monitored by infrared thermal imager, high speed camera and pressure sensor. The law of energy transformation in the process of contact explosion between molten aluminum and water was analyzed. The experimental results show that film boiling occurs instantaneously when molten aluminum liquid is in contact with water at high temperature. The shock produced by intense gasification of water produces disturbance in water and the disturbance expands rapidly. After 40ms, the film boiling changes to the nucleate boiling until explosive splashing occurs. According to the law of energy conservation, explosive shock theory and experimental results, the potential thermal energy of high temperature molten aluminum is about 3.34%~11.23% and converted into explosive shock wave energy. |
