Abstract:
A series of experimental measurements were conducted in
a baffle stabilized turbulent jet spray flame and a
baffle stabilized pool fire in an effort to provide an
improved understanding of the influence of various
parameters on the processes controlling flame stability.
The importance of a number of parameters including the
agent injection duration, air velocity, air temperature,
and system pressure were tested. A comparison of flame
stability in pool fires and spray flames showed that for
similar air flows and baffle sizes, baffle stabilized
pool fires were more difficult to extinguish than baffle
stabilized spray fires. For small air flows, the agent
required to extinguish the pool fires was similar to the
peak flammability limits related to premixed flames.
