垂直壁面火蔓延速率的实验测量

垂直壁面火蔓延过程受材料本身的热物理性质以及外加辐射等复杂因素条件的影响很大，论文研究建立了可测量不同材料存在外加辐射条件下的垂直方向火蔓延实验台，来研究典型可燃物的垂直方向火蔓延特性，观察不同材料之间火蔓延行为的不同，同时测定可燃物的火焰到达高度随时间的变化情况，得到相应的火焰蔓延速率。同时考虑外辐射情况下对不同材料垂直方向火蔓延过程的影响，实验数据可为进一步的模拟研究工作提供很好的参考。

The Experimental Measuring of Vertical Flame Spread Speed

The vertical flame spread procedure is affected by many factors, such as the material's thermal physical properties and external radiation. This letter mainly focus on the vertical flame spread characteristics with the different materials, which were measured by building a flame spread experimental bench with external radiation. The variations of flame location with time and spread speed were obtained. The effects of external radiation on flame spread were compared for different samples. The test data will be used to verify the vertical spread simulation model which will be given in the further works.
