Book Description
The importance and contribution of the inherent flammability of polymeric materials to problems of fire safety is well recognized. This study was undertaken to provide a better understanding and interpretation of previous experimental investigations of polymer flammability. The structure of opposed flow diffusion flames has been measured by several investigators using both gaseous and solid fuels. The opposed flow diffusion flame is a convenient geometry for the study of the flammability of polymers because it allows both steady, diffusion controlled burning and extinction to be observed under well-controlled laboratory conditions. Conveniently available experimental parameters include fuel composition, oxidizer composition, and oxidizer blowing rate. Reported experiments generally have not included the variation of pressure or temperature. Radiation effects, which are important in fires, remain to be well-characterized in laboratory studies of opposed flow diffusion flames where radiation generally is of minor importance.

Book Description
Structural measurements were obtained and compared with other investigations of diffusion flames. Departures from the commonly assumed collapsed flame model of laminar diffusion flames were observed in terms of excessive CO concentrations and oxygen penetration into the fuel side of the flame. An upper bound on the importance of oxygen diffusion to the fuel surface and subsequent surface oxidation was placed at 20% of the energy required for fuel pyrolysis, with the remainder of the energy being delivered to the surface from the flame through heat transfer processes. As the oxygen concentration in the oxidizer flow was decreased and extinction conditions approached, the CO/CO2 ratio at the flame increased slightly, the oxygen concentration at the luminous flame zone decreased, the flame stand-off distance decreased, and the flame temperature decreased. Radial similarity in the composition and temperature profiles was established experimentally which confirms predictions and greatly simplifies the modeling of the opposed flow diffusion flame.
