Wall Flames and Implications for Upward Flame Spread
James Quintiere, M F. Harkleroad, Yuji Hasemi
New Concepts are addressed for predicting he flame spread on materials from laboratory measurements. It focuses on heat transfer which precipitates and preces upward flame spread on a verticl surface. Six materials have been eatured 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 resuls 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. Experimenal results yield flame height proportional to energy release rate to the 2/3 power and wall hea 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 1.4m.
