A series of experiments was conducted on
baffle-stabilized spray flames in an effort to provide
an improved understanding of the influence of various
parameters on the processes controlling flame
suppression. Measurements were made of the agent mass
required to suppress the spray flames as a function of
the agent injection duration (which was designed to
deliver a constant mass flow of agent to the burner for
a controlled duration), the air velocity, the oxidizer
temperature, the ambient pressure, and the fuel flow.
The agent mass fraction required to extinguish the flame
was estimated from the agent mass divided by the agent
injection duration. Extinction measurements were
performed with the gaseous agents CF3Br, CF3I, C2HF5
(HFC-125), and C3HF7 (HFC-227ea).
