The analysis of recent experiments (NIST TN 1423) using
JP-5 and JP-8 pool fires performed in 15 m and 22 m high
hangars suggest that plume center line temperature
correlations found in the computer fire model FPETool
(NISTIR 5486-1) under predict the ceiling temperature
for large fires. The analysis was based on the results
of thirty-three fire tests which had heat release rates
ranging from 100 kW to 33 MW and ambient temperatures
ranging from 8 deg C to 31 deg C. The ceiling jet
correlation also requries modification since a
comparison of predicted sprinkler activation using
FPETool to measured sprinkler activation met with only
limited success. The purpose of this paper is to
present a new plume algorithm for the predicted
sprinkler activation using FPETool to measured spirnkler
activation met with only limited success.
