“…The values obtained were σ/nm = 0.550 and (ε/k B )/K = 590. These values also predict the viscosity values of Vogel and Strehlow [38] within ± 2.5 %, as shown in Fig. 1.…”

“…The density values employed were obtained by the equation of state of Span and Wagner [16]. Among the primary data, the data of Vogel and Strehlow [38] were key to determination of the viscosity of the dilute gas. These data were measured with an absolute oscillating-disk viscometer on a high-purity sample of hexane and covered the temperature region from (298 to 631) K with pressures from 0.01 to 0.31 MPa.…”

“…The relative expanded uncertainty u(η) of each data set is at 95 % confidence. fit the data of Vogel and Strehlow [38] with an expanded uncertainty of ± 0.3 % with these five fit parameters, given in Table 2. Figure 1 shows the data of Vogel and Strehlow [38] along with the correlation of Eqs.…”

“…The data of Vogel and Strehlow [38] were measured over a range of density, and experimental values for the second-virial-coefficient of viscosity can be determined from these data due to their low uncertainty. Figure 2 shows these experimental values for B η with error bars, along with the theoretical curve from the theory of Rainwater and Friend [19,20].…”

This article summarizes the correlation procedures developed for IUPAC Project 2012-040-1-100 [Reference correlations for the thermal conductivity and viscosity of fluids over extended range of conditions (vapor, liquid and supercritical regions)]. This project is focused on the development of wide-range reference correlations for the thermal conductivity and viscosity of fluids that incorporate as much theoretical knowledge of these properties as possible. The thermal conductivity and viscosity correlations developed here for pure fluids are functions of temperature and density. The best available equations of state for a given fluid are used to calculate the thermodynamic properties required for these correlations, often from measured temperatures and pressures. The correlation methodology developed during this project has been applied to hexane in this report but can be applied to any pure fluid with a reliable equation of state and reliable data for the thermal conductivity and viscosity over a significant range of temperatures and densities.

We describe models for the viscosity, thermal conductivity, and surface tension for selected fluids implemented in version 10.0 of the NIST computer program, NIST Standard Reference Database 23, also known as NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP). These fluids do not presently have published reference fluid quality models in the open literature, so we provide preliminary models based on available data as an interim measure to allow calculations of these properties. Comparisons with available experimental data are given.
