运用CFAST区域火灾模拟软件,针对一个典型的民用建筑起火房间进行火灾模拟计算,得出着火房间在不同的热释放速率条件下,通风口的开与关所对应的烟气层温度、空气层温度、烟气层界面高度以及烟气层内的O2浓度、生成的CO2和CO浓度的影响。结合各参数进行数据处理,得出相应的变化曲线,并对曲线进行了详细分析。
The CFAST fire simulation software is used to simulate the fire in a typical fire building in a civil building. The results show that the flue gas temperature, the temperature of the air layer corresponding to the opening and closing of the vent under different heat release rates, , The height of the flue gas layer interface, the concentration of O2 in the flue gas layer and the concentration of CO2 and CO generated. Combined with the parameters of data processing, draw the corresponding curve, and a detailed analysis of the curve.
