针对广泛应用于超燃冲压发动机的吸热碳氢燃料,简要介绍了用于模拟燃料热物理特性的替代燃料方法和广义对应状态法则.以大庆RP-3航空煤油为例,选择了一个由49%（摩尔比）正十烷,44%1,3,5-三甲基环己烷以及7%正丙基苯组成的替代煤油用来模拟RP-3航空煤油进行热物理特性研究,并采用广义对应状态法则对替代煤油热力学和输运特性进行了数值研究.在此基础上,提出了预测超临界态流体通过音速喷管流量的新方法并得到了实验验证. |

To investigate the thermophysical properties of endothermic hydrocarbon fuels, the method of fuel surrogate and principle of the extended corresponding states （ECS） were reviewed briefly. A three-species surrogate consisting in mole of 49% n-decane, 44% 1,3,5-trimethylcyclohexane, and 7% n-propyl-benzene was selected to simulate the thermophysical and transport properties of Daqing RP-3 aviation kerosene. A new method has been proposed to predict the mass flow rates of a supercritical fluid through a sonic nozzle. Agreement was obtained when comparing the calculated flow rates with measurements. |
