Recent international agreements call for a halt to the
manufacture of CF3Br (Halon 1301), a commonly used halon
fire suppressant, due to its high ozone-depletion
potential. Ideally, the search for replacement
compounds should be guided by fundamental studies of the
detailed inhibition mechanisms of halogenated agents in
flames. A large number of experimental and modeling
studies have investigated the impact of halogenated
inhibitors in premixed systems. Few studies, however,
have investigated the detailed structure of nonpremixed
flames with chemical inhibitors added to the oxidizer
stream, a configuration that more closely corresponds to
realistic fire situations. In an effort to construct a
paradigm of flame inhibition by halogenated compounds,
an experimental and numerical investigation of the
effect of chloromethane addition to the oxidizer stream
of counterflowing nonpremixed flames was conducted.
