  • In order to select the surrogate fuel with the same physical and chemical properties as RP-3 kerosene, the physical and chemical properties of RP3 kerosene were analyzed. According to the physical and chemical properties of RP3 kerosene, the selection criterions of the RP3 kerosene surrogate fuel (including the molecular mass, hydrogencarbon ratio, cetane number and lower heating value) were determined. Based on the selection criterions, a fivecomponent RP-3 kerosene surrogate fuel comprising ndecane, n-dodecane, iso-cetane, methylcyclohexane and toluene was presented, and the mole fractions of these five components were optimized. Furthermore, the densities and kinematic viscosities of the surrogate fuel and RP3 kerosene were contrastively analyzed at different temperatures. The results show that the molecular mass, hydrogencarbon ratio, cetane number and lower heating value of the surrogate fuel, which comprise 14% ndecane/10% ndodecane/30% isocetane/36% methylcyclohexane/10% toluene (mole fraction), agree well with the corresponding criterions of RP3 kerosene. At the same time, the variation trends of the densities and kinematic viscosities of the surrogate fuel agree well with the corresponding experimental data of RP3 kerosene at different temperatures.
