Abstract:
The purpose of this study is to examine the predictive
capabilities of fire models using the results of two
fire experiments conducted in an aircraft hangar with a
ceiling height of 14.9 m (49 ft.). The fire experiments
were conducted at Barbers Point, Hawaii by NIST in
conjunction with the United States Navy. This study is
designed to investigate fire model applicability at a
ceiling height where only a limited amount of
experimental data is available. Some earlier efforts to
compare computer fire models with experimental data at
heights above 14 m include Walton, Duong and Notarianni
and Davis. Model predictions compared with the
experiments include: plume centerline temperature at
the ceiling, temperature, ceiling jet velocity, draft
curtain filling and spilling times, temperature
variation across the draft curtain and smoke detector
activation. The fire models included in the study are
the plume correlations of Heskestad and McCaffrey, the
ceiling jet correlation of Alpert, the zone models
CFAST, FPETool, and LAVENT, and the computational fluid
dynamics models (CFD) CFX and LES.
