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.
