Calculations have been performed for co-flow diffusion flames of propane and a propane-ethanol-water fuel mixture, prescribed for the Federal Aviation Administration (FAA) Aerosol Can Simulator, in the cup-burner configuration, with added CF3Br and C2HF5. The time-dependent, two-dimensional numerical code, which includes a detailed kinetic model (177 species and 2986 reactions) and diffusive transport, has predicted the minimum extinguishing concentration of agent and revealed the unique two-zone flame structure causing combustion enhancement by C2HF5 in zero gravity.
