Ignition risk analysis of common building material cylindrical PMMA exposed to an external irradiation with in-depth absorption

The Poly methyl methacrylate (PMMA) material with a cylindrical shape are widely used for the building components. Under external irradiation, it may be ignited by a pilot ignition. Previous studies focused more on a flat surface sample, while for a cylindrical configuration, the heat flux distribution, solid-phase temperature profile and ignition time establishes different aspects induced by the cylinder curvature. Therefore, this study...
