Abstract

The attenuation of an incident radiant heat flux by pyrolysis volatiles when heated under a resistance element radiant heater, a phenomenon that is not well understood, is studied by simulated experiment and mathematical models. The radiation attenuation of an incident heat flux when pine or PMMA is heated (6—14%) obviously commences before ignition, although it is not as large as the result reported by Kashiwagi (50—80%) using a laser radiant heater. The calculated results clearly indicate that ignition models must consider radiation attenuation by pyrolysis volatiles.
