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.

Self-consistent calculations of interaction pVT-virial coefficients B 12 (T ), viscosities η mix (T ), and diffusion coefficients D 12 (T ) of binary mixtures of the alkanes C n H 2n+2 (n < 6) are presented. This study is based on the recently developed model of the (n-6) Lennard-Jones temperature-dependent potential (LJTDP) and uses already obtained potential parameters of the pure alkanes as input data. The well-known and simple Lorentz-Berthelot (LB) and the more elaborate Tang-Toennies (TT) mixing rules are applied to the potential parameters of the pure alkanes in order to determine those of the mixtures. The new Hohm-Zarkova-Damyanova (HZD) mixing rule, which is an extension of the TT-mixing rule, is also considered. The HZD takes into account that for the LJTDP model, in general, the repulsive parameter is an independent variable whose value n = 12. As in a recent examination of binary mixtures of globular molecules, the LB-mixing rule is superior to TT-and HZD-mixing rules when calculating equilibrium properties such as B 12 (T ). For the transport properties η mix (T ) and D 12 (T ), the new mixing rule performs slightly better.
