The forced flow driven flame spread behavior along an array of discrete wooden fuel elements was experimentally investigated, which could be an important step to understanding the flow-flame interactions that govern fire spread. Fuel arrays with five different spacings (0.75, 0.875. 1.00, 1.125, and 1.25 cm) were subject to flow speeds ranging from 2.2 to 4.3 m/s at approximately 0.2 m/s intervals. For spacing-flow speed conditions tested in the current study, the flame spread behavior was categorized into three different regimes, continuous, discrete, and quenching, and the regimes were presented in a flammability map. Visual analysis of top and side view video data were used to describe the changing flame behavior and increasing discretization of the overall flame structure as the flow speed increases. An analysis of the fluid mechanics and heat transfer conditions revealed a correlation between the Stanton number (St), the Damkohler number (Da), and the onset of flame instabilities and quenching.

实验研究了沿着离散的木质燃料元件阵列的强制流动驱动的火焰蔓延行为，这可能是理解控制火焰蔓延的流焰相互作用的重要一步。具有五个不同间距（0.75、0.875、1.00、1.125和1.25 cm）的燃料阵列以大约0.2 m / s的间隔经受2.2至4.3 m / s的流速。对于当前研究中测试的间隔流速条件，将火焰蔓延行为分为三种不同的状态：连续，离散和淬火，并在可燃性图中显示了这些状态。俯视和侧视图视频数据的视觉分析被用来描述随着流动速度的增加，火焰行为的变化和整体火焰结构离散的增加。St），Damkohler数（Da）以及火焰不稳定和淬火的开始。
