采用模拟实验的方法 ,研究了细水雾对障碍物后隐藏火焰的抑制效果。实验发现 :对于水平方向施加水雾 ,能够有效地抑制火焰。通过与哈龙灭火剂灭火有效性进行对比 ,发现在有障碍物时 ,细水雾灭火效率尚待提高 The effect of water mist on the concealed flame after the obstacle is studied by the method of simulation experiment. The experiment found that applying water mist to the horizontal direction can effectively suppress the flame. By comparing with the effectiveness of Halon fire extinguishing agents, we found that the fire extinguishing efficiency of water mist needs to be improved in the presence of obstacles
