“…The procedure for the development of chemical surrogates for gasoline and diesel fuel can certainly be inspired from the strategy well stated by Ranzi et al [309][310] in two papers describing the formulation of a JP-8 surrogate fuel. This strategy was the following: "1.…”

“…The validation of the models for these binary mixtures, which can be considered as surrogates for diesel fuel, was performed using experimental data obtained in a flow reactor. A model for a surrogate of kerosene containing n-dodecane, isooctane, methylcyclohexane, benzene and toluene has been written [309] and validated under flame conditions [322]. Models for still more complex fuels have been obtained by adding high temperature lumped reactions for n-tetradecane and decalin [310].…”

“…Furthermore, thermophysical property data are unavailable for many of these species. This issue is addressed for the JP-8 tests by using a surrogate 1 proposed by Violi et al [16] to represent the fuel during T c calculations. For the HRJ fuels, which are greater than 99% paraffinic, we can calculate T c using the thermophysical properties of any single paraffin.…”

“…2. The JP-8 TIC is characterized by large peaks for each of the normal hydrocarbons between C 8 (n-octane) and C 16 (n-hexadecane). The other peaks correspond to iso-paraffins, cycloparaffins, and aromatics (15.7 vol.%).…”

Tonghun, "Ignition behavior and surrogate modeling of JP-8 and of camelina and tallow hydrotreated renewable jet fuels at low temperatures" (2012 b s t r a c tThe autoignition characteristics of the conventional jet fuel, JP-8, and the alternative jet fuels, camelina and tallow hydrotreated renewable jet (HRJ) fuels, are investigated using a rapid compression machine and the direct test chamber charge preparation approach. Ignition delay measurements are made at low compressed temperatures (625 K 6 T c 6 730 K), compressed pressures of p c = 5, 10, and 20 bar, and equivalence ratios of / = 0.25, 0.5 and 1.0 in air. The HRJ fuels ignite more readily than JP-8 for all tested conditions, consistent with derived cetane number data in the literature. The camelina and tallow HRJ fuels exhibit similar autoignition characteristics, but the two fuels can be distinguished under stoichiometric conditions. Kinetic modeling is conducted with a 2-component surrogate (10% n-dodecane/90% 2-methylundecane) and a single component surrogate (2-methylnonane) to evaluate the potential to predict ignition behavior of the HRJ fuels. Modeling results indicate that the surrogate fuels can only provide useful predictions at a limited set of conditions (p c = 5 bar and / = 1.0), and that the agreement of the model and experimental data improves with decreasing compressed pressure. Under most conditions, the 2-component surrogate provides better prediction of ignition behavior, but the single component surrogate is superior at low pressures near the negative temperature coefficient region.

“…For kerosene's complex constituents, suitable surrogate fuel model was always adopted. The surrogate fuel model has been widely studies both in China and aboard, which included single component, three components and six components model [5][6][7] .Honnet, et al [9] from Aachen University developed a two components model (80% n-decane+20%trimethylbenzene) and validated the mechanism through shock tube, rapid compression machine, and premix combustion experiments.…”

Abstract. Spontaneous emission signal had different curves of kerosene's auto-ignition in shock tube under different temperature conditions, and OH * radicals concentration time history was numerically investigated. Two component surrogate fuel model (n-decane+trimethylbenzene) was used to validate consistency of its ignition delay time data with kerosene. Then simulation of OH * time history during reaction was carried out using the surrogate fuel model's combustion mechanism. OH * radicals' sensitivity analysis and reaction paths of production and consumption were investigated under different temperatures. The results show that the difference of dominant reactions for radicals' consumption lead to different curves of OH * radicals traces, which was that two peaks curve would present more easily under lower temperature and one peak curve under higher temperature.
