| 中文摘要: |
| 轰燃后火焰的热辐射危害 ,是目前确定建筑物间安全距离的主要依据之一。该文提出了轰燃后火焰在室外一定距离处辐射热通量的计算方法 ;并在喷出火焰不受室外风影响的情况下 ,利用小规模试验的结果对这一方法进行了验证. |
| 英文摘要: |
| Current practice in predicting safe separation distances between buildings relies on an assessment of the radiant hazard posed by post flashover flames. A method is proposed for calculating the radiant heat flux of post flashover flames to surfaces outside a vertical vent. An experimental study is made in reduced scale compartment to examine the validity of the method for extrusive flames unaffected by wind. |
