摘要：Hydrogen and five short-chain hydrocarbons are mixed with RP-3 aviation kerosene (RP-3) to study their blending effects on the combustion of RP-3. Seven combustion characteristics, the ignition delay time, burnout time, adiabatic flame temperature, extinction temperature, rate of production of hydroxyl radicals, laminar flame speed, and extinction strain rate, are simulated in four different reactors. The simulated data are preprocessed to match the requirements for a variation disturbance method proposed in this paper, and then the disturbance is obtained for representing the total influence of hydrogen and five short-chain hydrocarbons blending on the combustion properties of RP-3. The results show that H-2, CH4, and C2H4 have a greater degree of disturbance to RP-3. In contrast, the influence of C3H6 is the weakest. The rate of disturbance shows that H-2 and C2H4 have a positive effect on each of the combustion characteristics, and especially, C2H4 plays a promoting role in the combustion performance of RP-3. The reaction paths of seven fuels are analyzed by time-integrated element flux analysis, and the viability and rationality of the variation disturbance method are supported by the calculation of branching ratios of six main reaction channels.
