在大气压和443 K的含燃料流温度下，在逆流配置中测量了n-C14 H30、n-C16 H34、石油衍生的JP-5喷气燃料、亚麻衍生的加氢处理的可再生JP-5喷气燃料、石油衍生的F-76柴油燃料和藻类衍生的加氢处理的可再生F-76柴油燃料的预混和非预混火焰的熄灭应变速率。用新近发展的动力学模型模拟了n-C_（14）H_（30）和n-C_（16）H_（34）火焰的实验数据。计算结果与预混火焰的数据非常吻合，而非预混火焰的数据被高估。n-C_（14）H_（30）和n-C_（16）H_（34）预混火焰的熄灭应变速率相似，而n-C_（14）H_（30）非预混火焰的熄灭应变速率比n-C_（16）H_（34）火焰的熄灭应变速率大。关于实际燃料，与生物衍生燃料相比，石油衍生燃料的火焰熄灭倾向更高。80%N的火焰熄灭应变率为1.5%。
Extinction strain rates of premixed and non-premixed flames of n-C14H30, n-C16H34, 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-C14H30 and n-C16H34 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-C14H30 and n-C16H34 flames are similar, while compared to n-C16H34, n-C14H30 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...
