- Abstract
- We have completed an initial computational study related to acid gas formation for two of the leading near-term Halon substitutes, FE-13 (CF₃H) and HFC-125 (C₂F₅H), and compared these results with Halon 1301 (CF₃Br). Our goal is to determine whether we can identify conditions under which HF production can be minimized for the same inhibiting power, a result that could have significant practical implications. Our approach is based on investigating possible differences in the kinetics of HF formation under different agent loading scenarios using premixed flame codes with CH₄/air as the combusting system. We consider the situation where suppressants are mixed with inert compounds such as N₂ and CO₂ and deduce the commensurate decreased in hydrogen fluoride yields to obtain the same degrees of suppressant capability. This work clearly illustrates the great potential of computational simulations as a tool for identifying specific agent configurations for maximized performance. Other areas of possible future application of simulations are indicated.
