为了认识细水雾灭火机理,寻找细水雾作用下的火焰熄灭边界,采用非线性突变理论分析了细水雾灭火过程,推导出火焰能量势函数及火焰临界熄灭温度的表达式,得到了细水雾扑灭正庚烷油盘火的火焰熄灭边界.进行了细水雾针对正庚烷油盘火的灭火实验,实验结果验证了火焰熄灭边界的正确性.相比吸热过程,火焰熄灭温度受氧浓度的作用更为迅速.
In order to understand the mechanism of water mist fire extinguishing and find out the flame extinction boundary under the action of water mist, a nonlinear catastrophe theory was used to analyze the water mist fire extinguishing process and to deduce the energy function of flame and the critical flame extinguishing temperature. Water Fight Fighting n-Heptane Oil Flame Fire Extinguish Boundaries. The water mist was applied to the n-heptane oil fire test, and the experimental results verified the correctness of the flame extinction boundary. Compared with the endothermic process, the flame extinguishing temperature By the role of oxygen concentration more rapidly.
