Abstract:

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.
