Abstract

The aim of this article is to examine the application of the hard-sphere scheme to the prediction of the viscosity and thermal conductivity of hydrocarbon mixtures, other than n-alkane mixtures. According to this scheme, mixture properties are calculated from the pure components properties. Hence these are obtained first. Furthermore, in addition to the temperature, the density is the important parameter rather then the pressure. A Tait-type equation is employed to successfully correlate the density of the pure liquids. Furthermore, in the first part of this article, a modified form of the equation proposed by Sun and Teja is employed in the scheme, to correlate the viscosity and thermal conductivity of pure alkyl benzenes, some alkanes, some cycloalkanes, and one naphthalene. Following this, the article focuses on the successful prediction of the viscosity and thermal conductivity of mixtures of these compounds.
