利用能够限制自然对流的水平窄通道, 对薄材料表面逆风传播火焰的三维效应进行了实验研究, 参数包括气流速度、氧气浓度、燃料宽度等.结果表明, 在足够宽的通道内, 火焰传播随燃料宽度的变化, 表现出随氧气浓度和气流速度的不同而变化的三维特性.侧面热损失和氧气扩散对火焰传播的影响, 在各种氧气浓度和气流速度下, 都限于燃料宽度小于10倍扩散长度 |

The three-dimensional effects of flame spread over thin materials were experimentally studied using a natural-convection-suppressing horizontal narrow-channel, and the gas flow speed, oxygen concentration, and sample widths were altered. In a sufficiently wide narrow-channel, variation of flame spread with the width of material sample shows different trends for different gas flow speed and oxygen concentration. In all the tests, the effects are limited to the samples whose widths are less than 10 times of diffusion length |
