摘要

JP-10是煤油型喷气燃料中比冲最高的燃料，是石油和航空工业的重要燃料。因此，对JP-10热力学性质的高预测性能是高保真计算分析所必需的。为了准确有效地预测JP-10的热力学性质，建立了扩展的Redlich-Kwong-Peng-Robinson (eRK-PR)状态方程(EoS)。提出了一种新的δ参数约束条件以及实验临界压缩系数(Zcexp)与EoS临界压缩系数(ZcEoS)之间的相关性，以扩大Redlich-Kwong-Peng-Robinson EoS的可用Zcexp范围。随后，对eRK-PR EoS在8种测试化合物和JP-10上的预测性能进行了评估。将预测的9种纯化合物的热力学性质与使用各种eos和国家标准与技术研究所的数据得到的结果进行了比较。结果证实，eRK-PR EoS比其他EoS更准确地预测了JP-10的热力学性质。

Improved prediction of the thermodynamic properties of JP-10 using an extended Redlich-Kwong-Peng-Robinson equation of state

JP-10 is an important fuel in the petroleum and aviation industries because it has the highest specific impulse among kerosene-type jet fuels. Thus, a high predictive performance for the thermodynamic properties of JP-10 is necessary for high-fidelity computational analysis. To accurately and efficiently predict the thermodynamic properties of JP-10, the extended Redlich-Kwong-Peng-Robinson (eRK-PR) equation of state (EoS) is developed. A new $δ$ parameter constraint condition and correlation between the experimental critical compressibility factor ( $Z_{c}^{\exp}$ ) and the critical compressibility factor of the EoS ( $Z_{c}^{EoS}$ ) are proposed to extend the range of the available $Z_{c}^{\exp}$ in the Redlich-Kwong-Peng-Robinson EoS. Subsequently, the predictive performance of the eRK-PR EoS is evaluated on eight test compounds and JP-10. The predicted thermodynamic properties of nine pure compounds are compared with those obtained using a variety of EoSs and the National Institute of Standards and Technology data. The results confirm that the eRK-PR EoS predicts the thermodynamic properties of JP-10 more accurately than the other EoSs.
