This paper presents the first measurements of the
burning rate of premixed flames inhibited by three
fluorinated hydrocarbons that have oxidation chemistry
which is similar to agents which may be used as
replacements for CF3Br. The burning rate of premixed
methane-air flames stabilized on a Mache-Hebra nozzle
burner was determined using the total area method from
schlieren images of the flame. The inhibitors were
tested over a range of concentrations and fuel-air
equivalence ratios. The measured burning rate
reductions are compared with those predicted by
numerical solution of the species and energy
conservation equations employing a detailed chemical
kinetic mechanism recently developed at the National
Institute of Standards and Technology (NIST). This
paper presents initial efforts at testing and validation
of the mechanism using burning rate data. The mode of
inhibition of these chemicals is inferred through
interpretation of the numerical results.
