This paper is built on the hypothesis that, as the heated area increases from a point source, a displacement flow is maintained until the heated area reaches a critical fraction of the floor area, after which there is a transition to mixing flow.This hypothesis is tested in a series of laboratory experiments with the investigation of thermal stratification and flow patterns produced by a range of area heat sources located on the floor of a naturally ventilated enclosure.
