摘要：

In order to investigate the effects of small molecule fuels on combustion characteristics of RP-3 aviation kerosene, detailed combustion models of RP-3 aviation kerosene alternative fuels was chosen and confirmed, and the models can accurately predict the combustion characteristics of RP-3 aviation kerosene and small molecule fuels. The objects of study are six kinds of blended fuels, which are formed by mixing six important fuels H2, CH4, C2H4, C2H6, C3H6 and C3H8 respectively with RP-3 aviation kerosene according to the proportion of 1:5 (molar ratio). The changes of auto ignition, burnout time, adiabatic flame temperature, extinction temperature and species concentration of each blended fuel are analyzed under the parameters of equivalent ratio 1.0, pressure 0.1MPa and 1MPa. The influence of small molecule fuels on the rate of OH radicals generated is also discussed by means of ROP analysis method. Results indicate that C2H4 can shorten ignition delay time of RP-3 aviation kerosene by nearly 4.6%, while C3H6 will postpone the time by 8.4% and, moreover, C2H4 and H2 have a positive effect on the fast ignition and stable combustion of RP-3 aviation kerosene and the former plays a prominent role. © 2018, Editorial Department of Journal of Propulsion Technology.
