Abstract

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.
