| 摘 要： | 针对地铁站厅层的火灾特点,在自然通风的情况下,分别对有无细水雾作用的地铁站厅层火灾烟气情况进行数值模拟。得出火场内温度以及CO_2、CO、O_2的摩尔分数等烟气危险特性参数的变化和疏散安全指数的变化,指出细水雾对站厅层火灾烟气CO_2、O_2的摩尔分数降低作用明显,更利于人员安全疏散。

| Abstract: | Aiming at the characteristics of subway station hall fire and under the natural ventilation,subway station fire is simulated in the condition of water mist and the condition without water mist separately.The variation of hazardous characteristic parameters,including fire temperature,the mole fraction of CO2,CO and O2,and the changes of SI (safety index) are obtained.The collected data show that the effect of water mist in reducing the mole fraction of CO2 and O2 is obvious,that will help passengers in safety evacuation. |
