| 摘 要： | 研究池火灾燃烧火焰的基本特性以及热辐射传播规律.基于池火热辐射的危害性,引入点火源模型计算法和Mudan计算法两种模型化的热辐射计算分析方法.以乙醇为例,分析与液池中心距离、液池大小等因素对池火总辐射能、表面平均热辐射通量、热辐射强度的影响.结果表明,在离火源较近和较远的位置上,两种方法结果相近,此时两种模型都可以采用;而离火源中等距离的位置上,两种方法结果差异相对较大,Mudan计算法的结果相对保守.

| Abstract: | The basic characteristics of the pool fire and spread of the thermal radiation were studied.Based on the fire hazards of the thermal radiation,the characteristics of the pool fire were studied and two models of the thermal radiation calculation methods were introduced.Ethanol as an example,the distance from the center of the liquid pool,the liquid pool size and other factors on the impact of the total pool fire radiation,the average surface heat flux and the thermal radiation were analyzed.The results showe... |
