- Abstract
- A fire burning in an enclosure will cause a layer of warm combustion products mixed with entrained air to accumulate beneath the ceiling. With restricted ventilation, this layer can extend to occupy much of the room's volume. Eventually, some of the combustion proceses will occur in this vitiated layer. If sufficient oxygen is present, the fire can continue burning even when the environment is completely vitiated. In this presentation, a description will be given of experimental work concerning the formation rates of product species in turbulent, buoyant diffusion flames burning in these two-layered and fully-vitiated environments.
