Abstract

Abstract The present work is a continuation of our studies on predicting dilute transport properties of polyatomic gases consisting of sulfur hexafluoride (SF6), carbon tetrafluoride (CF4), and nitrous oxide (N2O). In this study, a good effective and isotropic pair interaction potential energy is obtained for each aforementioned system by the use of two-iteration inversion of the corresponding states of viscosity. A rather accurate correlation for the viscosity is reproduced from the inverted pair potential energy. The correlation for SF6 agrees with the literature data to within 1% in the temperature range 220 K
