Detailed chemical reaction mechanism of surrogate fuel for RP-3 kerosene

The ignition characteristics of RP-3 kerosene were measured in a chemical shock tube and the ignition delay times of RP-3 kerosene at various conditions were gained. According to the chemical compositions and physical properties of RP-3 kerosene, a surrogate fuel including n-decane, toluene and propyl cyclohexane(volume fraction of 0. 65, 0. 1, 0. 25) was provided, and the detailed chemical reaction mechanism for this surrogate fuel was developed. The ignition characteristics of this surrogate fuel in the chemical shock tube at various conditions were simulated using this detailed chemical reaction mechanism, and the simulation results were compared with the experimental data. The results show that the correlation for the logarithm of the ignition delay time of RP-3 kerosene and the reciprocal ignition temperature is linear under different pressures and equivalence ratios, and with the increase of ignition temperature and pressure and the derease of equivalence ratio, the ignition delay time is shortened. At the same time, the ignition delay times of this surrogate fuel computed by this detailed chemical reaction mechanism under different conditions agree well with the experimental data of RP-3 kerosene.
