“…This suggests that the performance of the instrument was affected by critical-point-related property changes that were not accounted for in the data analysis. The data by Kurin and Golubev 67 that were included in previous correlations were no longer considered in the present work because they appeared inconsistent with the data by Golubev and Petrov 62 at lower pressures and with those by Abramson 39 at higher pressures.…”

“…Fully included were the data of Kestin and Whitelaw, 59 of Docter et al, 60 of Vogel and Barkow, 54 and those of Hendl et al of 1993 55 as revised by Vogel in 2016, 23 as well as the data by van der Gulik 48 and Golubev and Shepeleva 61 in the liquid region. The comprehensive measurements of Golubev and Petrov 62 and the careful study of Michels et al 63 were carried out with capillary viscometers across the critical region where the compressibility increases strongly towards its singularity at the critical point. However, the working theory of this type of instrument was at that time only applicable to incompressible fluids.…”

“…47 For lack of instrument details, the extended working theory by van den Berg et al could not be applied to correct the data set of Golubev and Petrov. 62 Therefore, some points in regions of high compressibility were excluded from these data sets for the development of the new viscosity correlation. For reasons of internal consistency, only a subset of the data by Haepp 66 was used from 370 K to 450 K with pressures from 3 MPa to 150 MPa.…”

“…Compared with the new correlation, which was not adjusted to the data of Sih et al ., 51 the deviations are shifted by about −1.2 % to the range from −2.1 % to −0.21 % with an AAD of 0.52 %. In that temperature and density range the new correlation is based on the data by Golubev and Petrov from 1953, 62 of Michels et al . of 1957, 63 and of van der Gulik of 1997, 48 which are mutually consistent within ±2 %.…”

A comprehensive database of experimental and computed data for the viscosity of carbon dioxide (CO2) was compiled and a new reference correlation was developed. Literature results based on an ab initio potential energy surface were the foundation of the correlation of the viscosity in the limit of zero density in the temperature range from 100 K to 2000 K. Guided symbolic regression was employed to obtain a new functional form that extrapolates correctly to T → 0 K and to 10 000 K. Coordinated measurements at low density made it possible to implement the temperature dependence of the Rainwater-Friend theory in the linear-in-density viscosity term. The residual viscosity could be formulated with a scaling term ργ/T the significance of which was confirmed by symbolic regression. The final viscosity correlation covers temperatures from 100 K to 2000 K for gaseous CO2, and from 220 K to 700 K with pressures along the melting line up to 8000 MPa for compressed and supercritical liquid states. The data representation is more accurate than with the previous correlations, and the covered pressure and temperature range is significantly extended. The critical enhancement of the viscosity of CO2 is included in the new correlation.
