UNIFAC Visco Group-Contribution Method for Predicting Kinematic Viscosity - Extension and Temperature-Dependence
The UNIFAC-VISCO group contribution method may be used to predict the kinematic viscosity. In this work the range of applicability of the method is extended. The interaction parameters for 24 pairs of groups have been determinated and the effect of the temperature is studied to predict the viscosity of mixtures over all the range for which they stay in liquid state.
