This is a final report dealing with new concepts 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
relevant flame spread measurements are presented. In
this particular study heat transfert 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 incalude
to serve as a guide to identifying the important
variables and their 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.
