| 摘 要： | 细水雾与火焰相互作用中雾滴主要是通过动量和雾卷吸进入火焰区,以达到抑制或扑灭火焰的效果.对细水雾与煤油火相互作用时雾卷吸现象及其影响因素进行了研究,初步确定了雾卷吸量的计算方法,对各种影响卷吸效果的因素做了研究,并进行了大量的灭火实验.实验结果表明:细水雾的卷吸效果随着雾通量增加而增加,随着雾滴粒径增加而减小.

| Abstract: | In the interaction of water mist and the flame, water droplets are involved into flame region mainly by momentum and water mist entrainment so as to suppress and extinguish fire. This paper investigated water mist entrainment and its influecing factors in the process of extinguishing the kerosene fire by water mist and proposed a method to calculate water mist entrainment quantity. The experimental results showed that the entrainment ability increases with the mist flux increasing, and decreases with the diameter of droplets increaseing. |
