Abstract:
A kinetic model of ignition and combustion of heavy $n$-alkenes ($n$-$\mathrm{C}_{10}\mathrm{H}_{22}$ and $n$-$\mathrm{C}_{12}\mathrm{H}_{26}$), benzene, and jet propellant Jet-A, hich is modeled by a BD surrogate consisting of $n$-decane $80\%$) and benzene $(20\%)$, is developed. The model is tested through comparisons with a large set of experimental data on the ignition delay time in both higher-temperature ($T>1000$ K) and low-temperature ($T = 650-950$ K) regions and also on the behavior of species concentrations during benzene oxidation in a flow-type reactor and during benzene combustion in a special burner. Other reaction mechanisms developed for the description of combustion of various surrogates modeling kerosene are briefly analyzed. It is demonstrated that the proposed model ensures a more adequate description of the measured ignition delay times than other known kinetic models, especially in the low-temperature range ($T = 650-950$ K). Specific features of the kinetics of low-temperature oxidation of the BD surrogate are analyzed.
