【摘要】 分析了北京某高校地下机房发生火灾时的火灾临界危险条件,采用STEPS软件建立了该地下机房火灾中人员安全疏散的模型,计算了人员安全疏散时间。应用烟气模拟软件CFX对该地下机房着火时温度和烟气高度的发展进行了数值模拟研究,据此得到人员安全疏散可利用的时间。结合该地下机房着火时的具体情况,计算了人员安全疏散所需的时间。并将计算结果与烟气模拟计算结果进行比较分析。更多还原

【Abstract】 The fire critical and risk conditions of the underground-room computer lab of a University in Beijing was examined,and a underground-room fire evacuation model was designed by using STEPS software,and the evacuation time calculation methods was identified.Numerical simulation of the temperature and smoke height inside the underground room was carried out by smoke simulation software CFX and the available and safe evacuation time for whole staff was determined.Considering the underground-room fire situation,the evacuation time was calculated.And the evaluation result and smoke simulation results was compared and analyzed.更多还原
