High-Accuracy, Temperature Dependent Density and Viscosity Measurements of a 50/50 JP-10 + Terpene Mixture

摘要

Densities of a 50/50 by volume mixture of JP-10 + a turpentine dimer fuel (TDF) have been measured in the compressed-liquid state from 270 to 470 K and at 0.5-45 MPa and at ambient pressure from 263.15 to 373.15 K. Ambient pressure dynamic viscosity has also been measured over the same temperature range. The density data have been correlated with a Rackett equation, and the compressed-liquid density data have been fit to a Tait equation. Correlation parameters are given. Results of the mixture measurements presented here are compared with previously measured densities of the individual components, TDF and JP-10. Measurements of density over large ranges of temperature and pressure, as well as viscosity measurements, provide information as to the suitability of a fuel for use as a drop-in replacement for traditional petroleum-based fuels. The large range in temperature and pressure of the measurements is important to more closely capture engine operating conditions and better access the potential of alternative fuel candidates.
