| 摘 要： | 以FDS模拟重庆开县某三合一场所火灾的全过程,再现火灾发生时的烟气、温度、能见度、CO体积分数等随时间的变化情况,通过提取火源附近壁面的温度信息,验证起火点的位置.通过对热释放速率、温度、CO体积分数随时间变化的分析,证实此次火灾中人员的死亡原因是高温和低氧的共同作用.模拟结果为火灾调查工作提供依据. |

| Abstract: | The procession of fire in Kaixian was successfully simulated by the CFD software as the Fire Dynamics Simulation.The results of heat release rate,temperature,visibility,carbon monoxide concentration were given.By picking up the information of temperature near the wall,the location of fire source was validated.The temperature and carbon monoxide concentration of stair hall versus time were analyzed and we found that the reasons of death were the lack of oxygen and high temperature rather than the high carbon... |
