摘要:
针对可燃物离散分布燃烧现象,基于外加辐射热流对火源燃烧速率的增长理论,考虑离散可燃物燃烧时 环境气压对燃烧速率增长系数 k 的影响,提出针对任意离散分布火源 i 的修正无量纲增长系数 Ki,Ki 值与离散分 布条件(火源中心间距 D 和火源数目 n2)有关,建立了离散火源燃烧速率计算模型.根据离散多火源自由燃烧燃 尽时间数据获得 Ki 经验式,对比分析多种离散分布条件下各火源燃烧速率的模型计算值和实验值,结果表明, 该计算模型结果比较合理.
Abstract:
Based on the growth theory of external radiation heat flux on fire burning rate,considering the influence of environment pressure on the growth coefficient k for fuel in discrete distribution,this paper puts forward a dimensionless correction growth coefficient Ki,which is related to discrete distribution conditions including center spacing D and fire resource amounts n2.A calculation model of fire burning rate is established.Besides,the Ki empirical formula is gained according to the free burn-out time data of discrete multiple fires.The contrastive analysis of the model calculation value and the experimental value of fire burning rate shows that the result by the calculation model is reasonable.
