How Accurate is Mathematical Fire Modeling
It is important to be able to predict the development of a fire in an enclosure of arbitrary complexity. A mathematical model valid for a single room, with multiple vents and objects in it has been developed. The fifth version of the model has just been completed; it is the Harvard Computer Fire Code V, or Mark 5 for short. In 1977, Factory Mutual Research Corporation carried out a series of eight well-instrumented full scale room fires, against which the single room model can be tested. The test fire room was 2.4 m x 9.6 m x 2.4 m high, with an open doorway; a slab of polyurethane foam in one corner, and a polyurethane foam target in a facing corner. The primary slab was ignited at its center, and the fire followed. The other tests were variants of this one. The authors compare the results of the calculations with the results of two of the experiments: the standard configuration and the case with a window replacing the doorway. The model 'predictions' are in good to excellent agreement for most of the variables. The disagreements are discussed.
