| 摘 要： | 利用FDS软件模拟火源在室内不同位置处火灾的危险性,分析火源在不同位置时室内烟气层的温度、氧气体积分数及烟气层高度的变化规律。模拟结果表明:火源在门开口径向方向时,室内1.5 m高度以下空间的烟气层温度较高,氧气体积分数较低,而1.5 m以上情况相反;火源位置距离开口越近,烟气层高度越低,危险性越大。

| Abstract: | The fire risk in different fire source positions is studied by using FDS.The impact of different fire source positions is simulated on smoke layer height,oxygen concentration and the temperature variations in vertical direction in the compartment.The simulations showed that when the fire source is in the radial direction of the door,the smoke layer temperature is higher and oxygen concentration is lower below the height 1.5 m.The law is reversed above the height 1.5 m;and the nearer the fire source position... |
