Abstract

At least three different physics based approaches to fire dynamics simulations have evolved over the years; lumped parameter or ''zone models'', computational fluid dynamics models based on classical trubulence modeling techniques, and large eddy simulations. Large eddy simulations provide the most realistic description of fire phenomena developed to date. All such simulations provide descriptions of the processes that control the mixing and combustion of fuel and air at elevated temperatures. In an enclosure fire these processes are complicated by the fact that the fuel was initially part of the building or its furnishings, and the air supply is controlled by the interaction of the fire with its surroundings. The geometry of the building and its furnishings influence the fire and are in turn changed by it. The rational prediction of these changes is one of the central issues in fire research. The key to understanding these phenomena lies at the interface separating the gas and condensed matter phases. Substantial institutional barriers hamper progress in this area of research.
