数值研究了燃料组成的不同对液滴蒸发和燃烧的影响。Jet-A用作液体燃料，Jet-A的替代燃料使用一种(正庚烷)、两种(正十二烷和1，2，4-三甲苯)和三种(正十二烷、异辛烷和甲苯)燃料。结果表明，在初始蒸发阶段，三组分替代燃料的蒸发速度较单组分替代燃料快，而在随后的蒸发阶段，三组分替代燃料的蒸发较慢。三种不同代用燃料的燃气温度演化差异在点火后即刻非常显著，但随着时间的推移逐渐减小。
The effects of difference in fuel components on the droplet evaporation and combustion are numerically investigated. Jet-A is used as liquid fuel, and one (n-decane)-, two (n-decane and 1,2,4-trimethyl-benzene)- and three (n-dodecane, iso-octane and toluene)-component fuels are used as the surrogate fuels of Jet-A. The results show that the evaporation of the three-component surrogate fuel becomes faster and slower than those of the one- and two-component surrogate fuels in the initial and subsequent evaporating periods, respectively. The differences in the gas temperature evolution among these three different surrogate fuels are remarkable right after the ignition, but become small with time.
