Corresponding-States Model for Viscosity of Liquids and Liquid Mixtures

Abstract

A corresponding-states viscosity model using oxygen, octane and water as the reference fluids was developed for a variety of liquids and liquid mixtures. The present model is generally accurate for most pure liquids being tested. A set of quadratic mixing rules is adequate to correlate the viscosity of non-aqueous solutions. Using an augmented asymmetric mixing rule to calculate the pseudo-critical temperature yields a good representation for the binary and ternary aqueous solutions. © 1993, The Society of Chemical Engineers, Japan.
