Short title	A fire plume entrains air, turns beneath the ceiling and feeds an upper smoke layer.
Image title	Room cross-section with a fire on the floor. A plume rises and widens as surrounding air is drawn into it from both sides. At the ceiling the plume turns into a ceiling jet spreading sideways, which feeds an upper smoke layer. The layer fades gradually downwards into cooler, clearer air below; there is no perfectly sharp boundary.
