分析火灾增长系数对舰艇机舱火灾氧气浓度的影响

Analysing Fire Growth Factor' s Effect on Fire Oxygen Concentration in the Ship Engine Room

针对舰艇机舱火灾中氧气浓度达到危险值的时间具有不确定性的问题,本文采用随机取值的方法得到火灾增长系数的分布,设定机舱火灾氧气浓度的危险值,通过工程算例得到舰艇机舱火灾中氧气浓度达到危险值时间的分布情况,对舰艇官兵进舱灭火战斗具有重要意义。

Because of the uncertain time when oxygen concentration reaches the risk value,this paper employs the random method to get the fire growth factor' s distribution,setting the risk value of fire growth factor,and getting the time distribution of oxygen concentration reaching the risk value.This paper has important significance on fire-fighting.
