Empirical Model of flame heat feedback for simulation of cone calorimetry
TL;DR: In this paper, a generalized flame model was developed for cone calorimeter tests for several polymers to develop a generalized heat feedback model, and the flame heat fluxes were partitioned into radiative and convective components based on an analysis of the materials' radiative fractions.

Polymer combustion and flammability—Role of the condensed phase∘
TL;DR: In this article, the effects of polymer characteristics on combustion and flammability are not nearly as well understood as those in the gas phase, and a nonhalogenated char-forming flame-retardant approach is suggested to improve the fire performance of polymers.

Characterization of flame spread over PMMA using holographic interferometry sample orientation effects
Akihiko Ito,Takashi Kashiwagi +1 more
TL;DR: In this article, the authors measured temperature distributions within the PMMA sample in the vicinity of the leading edge of the flame front using holographic interferometry and found that the heat flow vector patterns within the sample showed the dominant heat transfer path from the gas phase into the unburnt fuel ahead of the vaporization point.
