  • Ignition Temperature Histograms Ignition temperature determined for live samples Ignition temperature defined when a flame is first visible Distributions of ignition temperatures measured (see figure above)Purpose To better understand the combustion behavior of live fuels To add physics into forest fire modelingConclusion Sample types are important in determining ignition temperature Heat and mass transfer effects play an important role in sample heat-up time Time to ignition significantly affected by size, shape and orientationFuture Work Improve technique to determine accurate ignition temperature and time to ignition Incorporate knowledge of leaf burning into models of bush burning Develop heat transfer correlations to avoid excessive computational costs
