“…94 The enhancement is significant only in a relative narrow window in temperature and density round the critical point. 2,7 Based on the previous studies, 3,5,6,[8][9][10][11][12][13][15][16][17][18] the viscosity critical enhancement of m-xylene is taken as zero. The total lack of industrial applications of m-xylene near its critical temperature and the existence of an only single experimental viscosity datum 39 further supports this choice.…”

“…This information is complemented with guidance available from theory to produce accurate, consistent, and theoretically sound representations of the transport properties over the widest range of thermodynamic states possible. The first fluid studied in this program was carbon dioxide 2 and since then a plethora of viscosity correlations have been produced, using the same philosophy, covering among others: simple fluids, 3-5 alkanes [6][7][8][9][10][11][12][13] and water. 14 Recently the work has been extended to cyclic and aromatic hydrocarbons.…”

A new correlation for the viscosity of meta-xylene (m-xylene) is presented. The correlation is based upon a body of experimental data that has been critically assessed for internal consistency and for agreement with theory. It is applicable in the temperature range from 273 K to 673 K at pressures up to 200 MPa. The overall uncertainty of the proposed correlation, estimated as the combined expanded uncertainty with a coverage factor of 2, varies from 1 % for the viscosity at atmospheric pressure to 5 % for the highest temperatures and pressures of interest. Tables of the viscosity, generated by the relevant equations, at selected temperatures and pressures, and along the saturation line, are provided.-1 -CONTENTS

“…Because there is little theoretical guidance concerning this term, its evaluation is based entirely on experimentally obtained data. The residual viscosity is often represented by polynomial series in density (or reduced density) that may have temperature (or reduced temperature) dependent coefficients [1,2].…”

“…For typical fluids, such as carbon dioxide [1], ethane [2], and water [5], the ratio Δη c (ρ, T)/η(ρ, T) exceeds 0.01 only within ± 1 % of the critical temperature of the fluid and near its critical density. In cases such as water [5], where there are reliable data for the viscosity very close to the critical point, the model of Bhattacharjee et al [29] has been shown to work well and is recommended for such fluids.…”

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.

SUMMARYA three-parameter corresponding states (CS) model is developed, importing methods formerly studied for the volumetric representation of #uids. The three parameters are critical temperature, pressure and a viscosity scaling factor de"ned from experimental saturated liquid viscosity data or, when these are unavailable, from a single experimental point. Two reference #uids are chosen both for their factor value and because the corresponding viscosity dedicated equations (VDE) are available. On the basis of the three-parameter CS model proposed by Teja et al. for volumetric properties, the reduced viscosity of a third #uid is obtained in reduced P, ¹ variables interpolating that of the two reference #uids, calculated at the same reduced temperature and pressure, by .Where the transport property is known along the saturation line at least, an improvement is introduced by correcting the factor with a temperature-dependent function "tted on these data. The model is then extended to mixtures using the one--uid model approach, in a completely predictive mode with respect to the mixture.The accuracy for both pure #uids and mixtures is comparable with that of the reference #uids' equations, while in the unimproved and improved mode the amount of input data is very limited. Also, comparison with a four-parameter CS model and with an ECS model con"rms the accuracy of the present technique. Considering the predictive nature of the model and the scattering of the available experimental data, the mean accuracy is good and more than satisfactory for the purposes of technical applications.
