“…Lin and Duan [11] suggested an empirical temperature-dependent volume correction to improve the performance of Peng-Robinson equation of state (PR-EoS) for describing the densities of liquids in the saturated region. Lin et al [12] presented a volume translation in terms of the critical properties and reduced temperature for improving the calculated densities of pure fluids and mixtures with the [13] proposed volume translations for vdW and PR-EoSs for improving the density computations of C 1 to C 20 n-Alkanes. For n-Alkanes, which were higher than C 20 , they used extrapolated amounts of Tc, Pc and ω. Tsai and Chen [14] proposed a volume-translated Peng-Robinson (VTPR) equation of state to improve the density predictions for some polar and nonpolar fluids.…”

“…For those n-alkanes for which experimental data were unavailable, correlations were used. The critical temperature was obtained from Tsonopoulos correlation [77], the critical pressure from [73] Magoulas and Tassios [78], the critical volume from Marano and Holder [79], and the Pitzer acentric factor from Han and Peng [80]. Arguments for selecting these correlations were presented elsewhere [81].…”

Models based on the corresponding-states principle have been extensively used for several equilibrium and transport properties of different pure and mixed fluids. Some limitations, however, have been encountered with regard to its application to long chain or polar molecules. Following previous studies, where it was shown that the corresponding-states principle could be used to predict thermophysical properties such as vapor-liquid interfacial tension, vapor pressure, liquid density, viscosity, and thermal conductivity of longchain alkanes, the application of the corresponding-states principle to the estimation of speeds of sound, with a special emphasis on the less studied heavier n-alkane members, is presented. Results are compared with more than four thousand experimental data points as a function of temperature and pressure for n-alkanes ranging from ethane up to n-hexatriacontane. Average deviations are less than 2%, demonstrating the reliability of the proposed model for the estimation of speeds of sound.

Modeling the Thermal Conductivity of Pure and Mixed Heavy n-Alkanes Suitable for the Design of Phase Change Materials

Recent interest in the use of paraffin waxes is related to energy management provided by phase change materials (PCMs) where a tunable melting temperature range is used to store or release latent heat by means of the solid-liquid phase change. Thermal conductivity is an essential property for the correct design of these new materials, with applications as different as household heating and insulation, clothes for athletes and campers, or solar energy storage. As the interest in most of these heavier n-alkanes was small until recently, the available data are particularly limited. The purpose of this work was to develop a simple and accurate model to estimate the liquid thermal conductivity of heavy n-alkanes suitable for the design of efficient PCMs. Corresponding states theory was selected, based on previous improvements for equilibrium and transport properties of pure and mixed heavy n-alkanes, using a second-order perturbation model on the Pitzer acentric factor. Results for the n-alkane series show that this new model is able to predict thermal conductivities in a broad temperature and pressure range with a deviation of 3%, whereas common deviations using a linear perturbation model are close to 16%. Results for one ternary and five binary mixtures indicate that the extension to mixtures is straightforward with the best results obtained using a mixing rule previously proposed for viscosity.
