Popis: | Timber is cost-effective and environmentally-friendly, which is a potential material for sustainable buildings, but its fire safety is still a significant concern. In this work, we investigate the burning behaviors of different types of woods and their self-extinction mechanism under external radiation. A unique near-limit flame is observed when the irradiation is above a critical value of about 40 kW/m2. Such a near-limit flame is weak, blue, and discrete that tends to attach to the wood residue surface, different from the normal buoyancy-controlled sooty yellow flame. If the irradiation is low ( |
