摘　　要：细水雾与火焰相互作用中雾滴主要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。本文对细水雾与油池火相互作用时雾卷吸现象及其影响因素进行了初步研究,通过建立一个简单的模型,初步确定了雾卷吸量的计算方法。所进行的小尺度模拟实验也对理论分析的结果提供了验证。Water droplets are involved into flame region by momentum and entrainment primarily to suppress or extinguish fire in the process of interaction between water mist and flame. In this paper, an elementary investigation of phenomena of water mist entrainment and its influence factors is conducted, and a calculation method of water mist entrainment is proposed by established a simple model. Several small scale tests have been performed to validate the result of theoretic analysis.
