Extinction strain rates of premixed and non-premixed flames of , , a petroleum-derived JP-5 jet fuel, a camelina-derived hydrotreated renewable JP-5 jet fuel, a petroleum-derived F-76 diesel fuel, and an algae-derived hydrotreated renewable F-76 diesel fuel were measured in the counterflow configuration at atmospheric pressure and a fuel-containing stream temperature of 443 K. Recently developed kinetic models were used to simulate the experimental data for and flames. The computed results are in close agreement with the data for premixed flames, whereas the data are over-predicted for non-premixed flames. Furthermore, the extinction strain rates of premixed and flames are similar, while compared to , non-premixed flames exhibit greater extinction resistance. Regarding the practical fuels, the extinction propensity of flames of petroleum-derived fuels is higher compared to bio-derived fuels. The extinction strain rates of flames of 80% toluene mixtures were computed also to evaluate the effects of addition of aromatics on extinction. The results confirmed that the addition of toluene increases the extinction propensity compared to neat flames under both premixed and non-premixed conditions, which explains partially the experimental results for petroleum- and bio-derived practical fuels.
