摘要提出了从实验室测量中预测材料上火焰传播的新概念。它着重于热传递的沉淀和之前向上火焰蔓延的垂直表面上。本研究以及过去的相关研究中有六种材料。介绍了它们的火焰传播特性。在这个特定的研究中，传热和火焰高度的结果，提出了在不同程度的外部辐照度燃烧的墙壁样品。还提供了甲烷线燃烧器壁火灾的补充结果。一个近似的理论分析，包括作为一个指导，以确定重要的变量和它们之间的关系的相关性的目的。实验结果产生的火焰高度成正比的能量释放率的2/3功率，和壁面热流分布大致相关的距离除以火焰高度。这些关系式似乎至少对这些实验的规模是成立的：火焰高度为0.3到1。
Abstract New concepts are addressed for predicting the flame spread on materials from laboratory measurements. It focuses on heat transfer which precipitates and precedes upward flame spread on a vertical surface. Six materials have been featured in this study as well as in past related studies. Their flame spread properties are presented. In this particular study heat transfer and flame height results are presented for wall samples burned at varying levels of external irradiance. Also complementary results are presented for methane line burner wall fires. An approximate theoretical analysis is included to serve as a guide to identifying the important variables and their relationship for correlation purposes. Experimental results yield flame height proportional to energy release rate to the 2/3 power, and wall heat flux distributions are roughly correlated in terms of distance divided by flame height. These correlations appear to at least hold for the scale of these experiments: flame heights of 0.3 to 1....
