Flame inhibition by CF/sub 3/Br
Technical Report
·
OSTI ID:6855616
A numerical model is used to investigate the properties of laminar flames inhibited by CF/sub 3/Br. Fuels include hydrogen, methane, methanol, and ethylene, with both oxygen and air as the oxidizers. A detailed chemical kinetic reaction mechanism for the fuel oxidation is combined with a mechanism describing reactions of CF/sub 3/Br and its halogenated products. The effects of CF/sub 3/Br on the flammability limits and burning velocity of laminar flames are predicted by the model, and the effects of variations in pressure, unburned gas temperature, and equivalence ratio on inhibition efficiency are examined. 4 figures, 4 tables.
