There is a high probability that gases or liquids with
high boiling points, higher than that of Halon 1301,
will be required to provide fire protection in engine
nacelles. In such complex flow environments, the
performance of the suppression agent will depend on a
number of parameters including physical properties of
the agent (heat capacity, boiling point, heat of
vaporization), the application temperature, and the
flow-imposed time constraints for liquid agent
evaporation. This work addresses the potential
performance of possible compounds via a computational
approach in order to eliminate unsuitable compounds from
consideration and determine favorable properties that
successful agents are likely to possess.
