Abstract / Description of output

Side-vented compartment fires are well described in the literature. Compartment fires with only a ceiling- vent are poorly understood in comparison. A series of 29 experiments in a reduced-scale, ceiling-vented compartment have been carried out to observe and characterise the four expected modes of burning. Ghosting flames and pool fire behaviour are both observed when the compartment temperatures are above 500°C, the former occurring at lower fuel loadings, the latter at higher fuel loadings. Pulsing behaviour is less common and exists at lower temperatures as a transition between other modes of burning. Asymmetric flow patterns can also occur with asymmetric arrangements of fuel or with very large ceiling vents.
