Abstract This paper presents the interaction between molten tin column and cooling water using the high-speed camera and the transient pressure measurement system. The effects of the molten tin column temperature, dropping height, diameter of molten tin column, and surrounding gas environment on the interaction of molten tin column with the water are examined. The results show that three modes of no explosion, product-outside explosion and product-inside explosion are observed. With the increase in the tin column temperature, no explosion is first shifted to product-outside explosion and then product-inside explosion with the maximum overpressure. The dropping height of the molten tin column promotes the intensity of the product-inside explosion. As the molten tin column diameter increases, the intensity of steam explosion first increases and then decreases. N2 atmosphere induces the stronger steam explosion than air.

熔锡柱冲击冷却水池的实验研究

摘要 本文利用高速摄像机和瞬态压力测量系统介绍了熔融锡柱和冷却水之间的相互作用。考察了熔锡柱温度、下落高度、熔锡柱直径和周围气体环境对熔锡柱与水相互作用的影响。结果表明，观察到了不爆炸、产品外爆炸和产品内爆炸三种模式。随着锡柱温度的升高，没有爆炸首先转变为产品外爆炸，然后是产品内爆炸，最大超压。熔融锡柱的下落高度提高了产品内部爆炸的强度。随着熔融锡柱直径的增加，汽爆强度先增大后减小。N2 气氛比空气引起更强的蒸汽爆炸。
