摘要
运用CFAST 3.1.7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,得出着火房间在同一热释放速率条件下,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、烟气层内的O2体积分数以及生成的CO2和CO体积分数的影响。对各参数进行数据处理得出相应的变化曲线,结合曲线进行分析,得出其变化规律。
Area fire simulation software of CFAST 3.1.7 was used on the fire room of a typical civil building fire in simulation.The influence of open and close of air vents on the flue gas temperature,air temperature,smoke layer interface height,flue gas concentration of O2 in the layer and concentration of CO2 and CO was obtained under the same heat release rate of room.The data for each parameter was used to draw the corresponding curve,and the change law of them was obtained by analyzing the curves.
