A computational study of extinguishment and enhancement of propane cup-burner flames by halon and alternative agents

Computations of cup-burner flames in normal gravity have been performed using propane as the fuel to reveal the combustion inhibition and enhancement by the CF3Br (halon 1301) and potential alternative fire-extinguishing agents (C2HF5, C2HF3Cl2, and C3H2F3Br). The time-dependent, two-dimensional numerical code used includes a detailed kinetic model (up to 241 species and 3918 reactions), diffusive transport, and a gray-gas radiation model. The...
