Viscosity prediction of pure fluids and mixtures in a corresponding-states framework
Giovanni Cristofoli, Maurizio Grigiante, Giancarlo Scalabrin
A three-parameter corresponding-states (CS) model is here developed importing methods formerly studied for the volumetric representation of fluids. Two fluids of the same conformal family are chosen both for their third parameter, here defined, and for the availability of viscosity-dedicated equations. On the basis of the three-parameter CS model form of Teja et al for volumetric properties, the reduced viscosity of a third fluid of the family is obtained in reduced pressure and temperature.
