Recent attempts to model the flow in very hot fire plumes where radiative transport of heat may significantly modify both the dynamics of the flow and the processes of combustion have met with only partial success. This paper gives an account of a model for the flow in a turbulent fire plume at the levels above which combustion is not appreciable but where strong buoyancy and radiation effects are still important. The model includes an analysis of the radiation field in which some approximations are made, but the main features are retained. In the treatment, the radiative flux is divided into lateral and vertical components which are considered seperately. An opacity is defined for the plume as the ratio of mean radius to mean free path of radiation, and the intermediate case in which this ratio is of order unity is discussed in detail. The role of large eddies which carry very hot gas to the edge of the smoke plume is emphasized, and an estimate is made of their substantial contributions to the reliative loss to the surroundings.
