摘要
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 pre-dict the thermodynamic properties of JP-10, the extended Redlich-Kwong-Peng-Robinson (eRK-PR) equa-tion of state (EoS) is developed. A new d parameter constraint condition and correlation between the experimental critical compressibility factor (Zcexp) and the critical compressibility factor of the EoS (ZEoS c ) are proposed to extend the range of the available Zcexp 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. CO 2023 The Korean Society of Industrial and Engineering Chemistry.
