建筑火灾中材料表面入射热通量确定方法简析

Incident Heat Flux on Surface of Flammable Materials in a Building Fire

可燃材料在火灾中的受热程度直接决定其实际的火灾危险性。材料表面的入射热通量是表征材料受热程度的关键参数。在综述现有文献的基础上,归纳总结了可燃材料在火灾中受热分析的基本理论和材料表面入射热通量的计算方法,这些基本理论和方法对正确评价材料的火灾危险性和模拟室内火灾的发展过程具有重要意义。

The fire hazard of the flammable materials in a building fire is depend on how their surfaces are heated due to the high temperature scene. The incident heat flux on surface of materials is a key factor to characterize the severity of suffering high temperature. In this paper,the fundamental theory on heat transfer and the calculations of incident heat flux in fire are reviewed and summarized,the results are very important to assess properly the fire hazard of flammable materials and to model the fire development.
