In this work, the physical properties of binary mixtures of n-heptane and 2,2,4-trimethylpentane were measured. Density and speed of sound were measured at temperatures ranging from (293.15 to 338.15) K, and viscosity was measured at temperatures ranging from (293.15 to 333.15) K. At 298.15 K, pure component values for heptane of 679.61 kg·m −3 , 0.389 mPa·s, and 1130.1 m·s −1 for density, viscosity, and speed of sound, respectively, agree with literature values. Similarly for 2,2,4-trimethylpentane, the values of 687.70 kg·m −3 , 0.501 mPa·s, and 1081.7 m·s −1 for density, viscosity, and speed of sound, respectively, agree with literature values. Density mole fraction and temperature data were fit to a secondorder polynomial. Bulk moduli ranged from (551.7 to 907.1) MPa over (293.15 to 338.15) K. Viscosity mole fraction data were fit using the three-body McAllister model, while the viscosity deviations were fit to a Redlich−Kister type equation. For the mixtures, an increase in mole fraction of 2,2,4-trimethylpentane resulted in an increase in density and viscosity and in a decrease in speed of sound, bulk modulus, and surface tension. Increases in temperature decreased density, viscosity, speed of sound, and bulk modulus. At room temperature, the surface tension values ranged from (18.7 to 20.3) mN·m −1 . These data can be used by researchers who are modeling the combustion process of mixtures of primary reference fuels and are modeling the physical properties of fuels.

The development of reference correlations for viscous fluids is predicated on the availability of accurate viscosity data, especially at high pressure, high temperature (HPHT) conditions. The rolling ball viscometer (RBV) is a facile technique for obtaining such HPHT viscosity data. A new, universal RBV calibration methodology is described and applied over a broad T-p region and for a wide range of viscosities. The new calibration equation is used to obtain viscosities for n-hexadecane (HXD),

In this work, the properties of mixtures of 1,2,3,4-tetrahydronaphthalene and trans-decahydronaphthalene were measured. Density and viscosity were measured at temperatures ranging from (293.15 to 373.15) K, and speed of sound was measured at temperatures ranging from (293.15 to 333.15) K. For the mixtures, increasing the mole fraction of 1,2,3,4-tetrahydronaphthalene and decreasing the temperature caused increases in density, speed of sound, bulk modulus, flash point, and surface tension. Mixture viscosities were lower than those of either component. Bulk moduli ranged from (1323 to 2092) MPa over (293.15 to 333.15) K. At room temperature, surface tensions ranged from (30.5 to 35.0) mN·m −1 , and flash points ranged from (328.7 to 343.1) K. The density, speed of sound, and bulk modulus of hydrodepolymerized cellulosic diesel (HDCD) can be matched by mixtures of 1,2,3,4-tetrahydronaphthalene and trans-decahydronaphthalene. The flash point and viscosity of HDCD are higher than those of the mixtures, while its surface tension is lower than those of the mixtures. If combustion is more sensitive to density, speed of sound, and flash point and less sensitive to viscosity, flash point, and surface tension, then a surrogate mixture for HDCD could contain 1,2,3,4-tetrahydronaphthalene and trans-decahydronaphthalene.
