Entropy Scaling of Viscosity – I: A Case Study of Propane

Published

Author(s)

Ian H. Bell

Abstract

In this work a broadly-applicable and simple approach for developing high accuracy viscosity correlations yielding uncertainties approximately equal to the uncertainties of the underlying data is presented. The approach is based on the combination of a number of recent insights related to the use of residual entropy scaling. The use of residual entropy as the independent variable ensures a model formulation that can provide guaranteed extrapolation behavior (barring errors in the equation of state itself), and provides reasonable predictions for viscosity even at extremes in temperature and density.
