“…For an aerospace vehicle of limited volume, increasing the energy density of the applied fuel can help reduce tank volume or extend flight range and/or increase payload without changing the fuel tank. The energy density of the fuel is directly determined by the density, and the density is always positively correlated with the former. − Viscosity directly affects the engine performance, the convective heat transfer process, the fluidity, and the atomization performance of fuels. − For example, low viscosity helps the injection of fuel into the nozzle, which relieves the pressure of the fuel delivery of a fuel atomization process. ,− Therefore, accurate measurement and detailed analyses of the physical data of surrogate fuels will contribute to the development of high-performance aviation kerosene for hypersonic aircrafts.…”

The actual composition is known to be highly responsible for the physical and chemical properties of a fuel. To understand the foundational physical properties of an aviation kerosene substitute mixture for hypersonic aircraft, n-undecane, butylcyclohexane, and 1-pentanol were used to construct a ternary system. The values of density (ρ) and viscosity (η) for the ternary system and three corresponding binaries were measured at temperatures T = (293.15 to 333.15) K and pressure p = 0.1 MPa. The Redlich−Kister equation was used to fit the excess molar volumes (V m E ) and viscosity deviations (Δη) of the binary systems, while those of the ternary system were correlated with four semi-empirical formulas (Cibulka, Singh, Redlich−Kister, and Nagata−Tamura equations). The experimental results show that the V m E values of the three binary mixtures have a positive relationship with the mole fraction of nonpolar components, while Δη values have a negative relationship. The non-ideal behavior of mixtures is discussed from the perspective of molecular interactions and structural effects. This work provides data support and guidance for fuel compatibility research.
