Abstract
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 (Zcexp) and the critical compressibility factor of the EoS (ZcEoS) 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.
