The proper use of computer fire models requies an
understanding of their applicability and limitations,
since all computer models are, at least to a certain
extent, empirically based. Equations or constants used
within computer models are frequently based on curve
fits to data from experiments. typically, the
experiments used to develop the correlations were
conducted under a limited set of conditions, e.g.,
compartment sizes, heat release rates or fire growth
rates. If the computer model is used for an application
that falls outside of the bounds of the experiments used
to develop the correlations, uncertainty may be
introduced. Additionally, inaccuracies can be
introduced in the numerical methods used to solve
integral or differential equations, or more simply in
math errors that were created during coding of the
program. This paper describes an evaluation of the
predictive capability of ASET-B. "Open calculations"
are used for comparisons with previously published
full-scale test data.
