Abstract:

The main limitation of current compartment fire models is that they generally are not capable of predicting fire growth, but are only suitable to calculate the consequences of a user-specified fire. An extensive database of fire curves would alleviate this problem, but the development of an exhaustive database of fire curves is not feasible. A more practical approach involves the use of correlations and sub-models, so that fire curves can be constructed for a variety of geometries and configurations on the basis of material properties from small-scale fire test data. Methods have been developed to predict the heat release rate vs. time of objects that are common in residences such as chairs and TV sets; and large objects such as automobiles and railcars. However, the most common geometry for which predictive sub-models have been developed is the room/corner test. Standard room/corner test protocols have been developed domestically (e.g., NFPA 265 and NFPA 286) as well as internationally (ISO 9705).
