Zone models simplify stratified and mixed compartment states. Based on Quintiere (2002), p. 3-162 and Cadorin and Franssen (2003), pp. 399–400.

Diagram for the article Fire dynamics (Fire Safety Academy wiki, level 1 Basic).

Short title	Hot upper and cool lower zones changing into one mixed compartment zone.
Image title	Left, two-zone model: a fire plume rises into a uniform hot upper zone above a uniform cool lower zone, with hot gas leaving and fresh air entering through a vent. Right, one-zone model: the whole compartment is one mixed zone with vent flows in and out. An arrow shows the change from the two-zone to the one-zone representation. Uniform zones are a model assumption, not the real temperature field.
