Extinction strain rates of premixed and non-premixed flames of n - C 14 H 30 , n - C 16 H 34 , 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 n - C 14 H 30 and n - C 16 H 34 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 n - C 14 H 30 and n - C 16 H 34 flames are similar, while compared to n - C 16 H 34 , n - C 14 H 30 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% n - C 16 H 34 + 20 % 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 n - C 16 H 34 flames under both premixed and non-premixed conditions, which explains partially the experimental results for petroleum- and bio-derived practical fuels.
