Autoignition of propane–air mixtures behind reflected shock waves

Development of a skeletal mechanism for diesel surrogate fuel by using a decoupling methodology

“…This is consistent with experimental observations from Haylett et al [86], who indicated that the difference in ignition delay at high temperatures small for various diesel fuels with different CNs. Thereby, the predictions for the present two surrogate fuels are capable of closely matching the measured ignition delay times at high temperatures for US #2 and F-76 diesel fuel from the experimental work of Penyazkov et al [84] and Haylett et al [86], even though the detailed composition of the tested diesel fuels are unknown.…”

“…Ignition delay times of diesel fuel/air mixtures were studied by Penyazkov et al [84] in a heated shock tube over equivalence ratios from 0.5 to 2.0 at p = 4.7-10.4 atm and T = 1065-1838 K. In this section, surrogate A listed in Table 1 was applied to predict the ignition delay time for a commercial US #2 diesel fuel tested in their experiments due to their similar H/C ratio and lower heating value. The experimental data of diesel fuel and the computational results using the present mechanism for n-decane, toluene, and the surrogate fuel at ϕ = 0.5 and 1.0 are shown in Fig.…”

A small detailed chemical-kinetic mechanism for hydrocarbon combustion

“…5d, 5e, and 5f show results of experiments [91] that were performed at different temperatures for fixed values of the density, instead of pressure. In these figures, densities of 0.62 or 0.66 kg/m 3 correspond to pressures of about 2.0 to 2.5 atm, and experiments at densities of 4.42 to 4.57 kg/m 3 correspond to pressures between 12 and 20 atm.…”

Autoignition delay times of propane mixtures under MILD conditions at atmospheric pressure

“…Penyazkov et al [26] measured the ignition delay times for lean, stoichiometric, and rich propane-air mixtures within a temperature range of 1000-1800 K and a pressure range of 2-20 atm. They provided an empirical correlation for ignition delay times by identifying two different slopes for temperatures lower and higher than 1300 K.…”
