摘　　要：为澄清有关烃类池火灾热辐射量化分析模型选择中存在的问题,针对"池火计算方法"模型进行量纲分析和物理意义方面的讨论,提出该模型在概念使用、量纲关系、热释放速率的计算以及池火焰模化等方面存在的问题。系统阐述点源模型、Shokri-Beyler模型、Mudan模型等常用烃类池火灾热辐射通量分析模型的适用条件和应用范围。点源模型适用于被辐射目标物从池火焰接受的热辐射通量小于5 kW.m-2情况下池火灾热辐射的量化分析;Shokri-Beyler模型主要应用于估算被辐射目标物从池火焰接受的热辐射通量大于5 kW.m-2的情况;Mudan模型可用于估算无风或有风条件下被辐射目标物从池火焰接受的热辐射通量。In order to clarify the issue of choosing quantitative analysis models for thermal radiation of hydrocarbon pool fires,a dimensional analysis and physical signification of ＂pool fire calculation method＂ model is discussed,and problems on concept,dimension,heat release rate and shape of pool flame of ＂pool fire calculation method＂ model are presented.The applicable conditions and application range for point source model,Shokri-Beyler model,and Mudan method are systematically illuminated,respectively.At heat flux less than 5 kW·m-2,the point source model is recommended to analyze quantitatively heat flux from pool fires.Shokri-Beyler model is most applicable at heat flux greater than 5 kW·m-2.Mudan method can be used for estimating thermal radiation flux from pool fires for no-wind conditions and windblown flames.
