Abstract
Several fire suppressants are under consideration to replace CF3Br for use in suppressing fires in aircraft cargo bays. In an FAA performance test simulating the explosion of an aerosol can, however, the replacements, when added at sub-inerting concentrations, have all been found to create higher pressure rise than with no added agents, hence failing the test. Thermodynamic equilibrium calculations as well as perfectly-stirred reactor simulations, with detailed reaction kinetics, are performed to understand the reasons for the unexpected enhanced combustion rather than suppression. The effectiveness of the suppressant is found to be highly dependent upon the mixing conditions of the reactants (through the local stoichiometry) for CF3Br, but not for C2HF5.Citation
