A brief overview of the main features to be represented by models of large fires, as understood from full scale experiments performed to date, will be provided. These features include spatial variations in temperature and heat flux, transient fluctuations in temperature and soot concentration, insight into the formation of soot from measurements of soot structure, the thermodynamic and chemical processes in the region near a liquid or solid fuel surface, the interaction of objects in wind, and the influence of wind on heat transfer from a large fire to an adjacent surface. Limited comparisons with existing theory and models will also be included. Areas where an improved understanding is needed to further develop and validate fire models will be highlighted.
