Catastrophe analysis of the water mist fire suppression process

摘要

摘要: 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.

Abstract: To understand the water mist fire suppression mechanism and find out the extinguishment boundary, the water mist fire suppression process was analyzed with a non-linear catastrophe theory. The expressions of the flame energy potential function and the flame critical extinguishing temperature were deduced. The extinguishment criterion for the n-heptane pool fire was obtained. The extinguishment boundary is verified by conducting the water mist fire suppression experiments on n-heptane pool fire. The effect of oxygen concentration on the flame extinguishing temperature is quicker than that of heat absorption.
