Abstract This paper evaluates the fuel moisture content (FMC) threshold that leads to fire extinction for a few fuel types under marginal conditions. Influences of fuel load, fuel depth, Leaf Area Index (LAI) and packing ratio on this FMC threshold were also analyzed. This aim was reached by applying numerical simulations performed with three approaches: a simplified physical fire spread model, a detailed fire physical model and an empirical criterion. Experiments at laboratory scale were also performed. Moreover, some Results published in the literature over the last years were presented and compared with theoretical outputs.

临界条件下导致灭火的燃料含水量阈值

摘要 本文评估了在边缘条件下导致几种燃料类型灭火的燃料水分含量 (FMC) 阈值。还分析了燃料负荷、燃料深度、叶面积指数 (LAI) 和填充率对 FMC 阈值的影响。这一目标是通过应用三种方法进行的数值模拟来实现的：简化的物理火灾蔓延模型、详细的火灾物理模型和经验标准。还进行了实验室规模的实验。此外，还介绍了过去几年发表在文献中的一些结果，并与理论输出进行了比较。
