Abstract:
A set of comparisons between a comprehensive room fire
model and a range of real-scale fire experiments is
presented. For these comparisons, a zone-based model,
CFAST ('consolidated fire and smoke transport' model) is
used. The model predicts the evolution of a fire in a
room and the subsequent transport of the smoke and toxic
gases which result from this fire. These comparisons
serve two purposes: to determine, within limits, the
accuracy of the predictions for those quantities of
interest to the users of the models (usually those
extensive variables related to hazard), and to highlight
the strengths and weaknesses of the underlying
algorithms in the models to guide future improvements in
this and other models. The predicted variables selected
for comparison deal with both of these purposes.
Although differences between the model and the
experiments were clear, they can be explained by
limitations of the model and of the experiments.
