Abstract:

This study was undertaken to help resolve the general flammability problem - namely, to predict heat release rates and fire spread rates in terms of readily measured material flammability properties. At present much of the problem is understood; however we do not have established procedures for predicting the radiative heat transfer to adjacent fuel surfaces. These predictions must be quite accurate because upward spread and burning processes are very sensitive to flame heat transfer from the flames due to positive feedback. The present work parallel Markstein's investigation of the radiant heat transfer blockage by the cold gas and soot near the fuel surface.
