Scale Model Flames for Determining the Heat Release Rate from Burning Polymers
The utility of flame size for the assessment of the heat release rate of burning polymers has been studied. Six polymers were tested in the NIST cone calorimeter to determine their heat release rate, and their flame height, area, and volume. A reduced-scale burner was developed for producing non-flickering, laminar flames, and tests were conducted with four gases, three liquids, and three polymers; subsequent automated image analyses again determined the flame size. The scaling for the flame size was shown to be reasonably well described by Froude modeling for turbulent pool fires or by laminar jet diffusion flame theory.
