聚合物燃烧火焰辐射及其温度的估算

受限空间中，通风对于燃烧状况和火焰辐射特性有重要影响。本文根据火焰中炭颗粒的生成及其受通风的影响，提出了关于聚合物燃烧火焰辐射和平均辐射温度的估算方法。计算了几种典型聚合物的火焰辐射及其平均辐射温度，并讨论了通风、燃料组成、炭颗粒和燃烧尺度的影响，旨在加深认识通风条件对于火焰温度及其有关辐射特性的影响，为受限空间中燃烧过程的分析提供依据。

Prediction of Flame Radiation and Temperature in Polymer Combustion

The influence of fire ventilation on flame radiation is important in enclosute fires espociallyfor undervenulated conditions. An approximate medeling methed for predicting flame radtantpower and mean flame radiation temperture for both well-and under-ventilated polymer fires isproposed, in which the role of flame sootiness as well as the effect of fire ventilation is consid-ered. The results were calculated for several typical polymers,and the effects of fire ventilation,chemical composition and structure of materials,soot particle concentration and fire size were al-so investigated. This study attempts provide a deeper scientific understanding of the effect offire ventilation on flame radiation and a scientific basis for the analysis of enclosure fires.
