“…In the straight-chain alkanes of aviation fuels, n -dodecane, n -tetradecane, and n -hexadecane are usually chosen as model compounds, while shorter alkyl cycloalkanes are considered to represent the cycloalkane category − among which methylcyclohexane and ethylcyclohexane are often adopted. For the priorities of pure methylcyclohexane or ethylcyclohexane, , the density data are abundant and have been reported by several research groups, − but various physical properties, such as density, thermal expansion, and compressibility of their binary mixtures with straight-chain alkanes, have been seldom focused on. Prak et al studied the densities, viscosities, speeds of sound, bulk moduli, surface tensions, and flash points of methylcyclohexane or ethylcyclohexane with n -dodecane or n -hexadecane at T = 293.15 to 333.15 K and P = 0.1 MPa, and through a comparison with these properties of petroleum-based fuels, it was found that ethylcyclohexane and n -hexadecane were the best matched for jet fuel.…”

In order to investigate the interactive effect on the density of two-component mixtures, six mixtures of methylcyclohexane(1) + n-dodecane(2)/n-tetradecane(2)/n-hexadecane(2) and ethylcyclohexane(1) + n-dodecane(2)/n-tetradecane(2)/nhexadecane(2) were measured by using the Anton Paar DMA 4200 M densimeter and a hand-operated pressure pump in the temperature and pressure ranges of T = 280 to 423.15 K and P = 0.1 to 9 MPa, respectively. Additionally, the combined standard uncertainty in the density of binary mixtures with n-hexadecane is u c (ρ) = 1.543 kg/m 3 , and for other mixtures, it is u c (ρ) = 1.541 kg/ m 3 . The experimental data were successfully correlated with the empirically modified Toscani−Szwarc equation of state with a maximum regression deviation of less than 1.0630 kg/m 3 for all the binary mixtures. On the basis of the experimental data and parameters of the regression model, isobaric thermal expansivity and isothermal compressibility were calculated and exhibited nonlinear behavior against the mole fraction, which is due to different molecular interactions between the two components.

In order to utilize thermal energy safely and efficiently, it is indispensable to elucidate the thermophysical properties of the medium with high accuracy. Regarding some media, such as water and HFC refrigerants, there are international standard values, contributing to the development of various heat engine institutions and process industries, and further improvement in accuracy has been attempted. On the other hand, however, thermophysical property information is remarkably insufficient for various types of media used for transporting energy and gases. In this paper, we introduce today's situation on fluid thermophysical properties and representative examples of thermophysical properties research.
