Predicting the viscosity of liquid mixtures consisting of n-alkane, alkylbenzene and cycloalkane species based on molecular description

摘要: Abstract 1-component Extended Hard-Sphere (1-cEHS) model has been developed recently to predict the viscosity of liquid, n-alkane mixtures. It represents a mixture by single pseudo-component characterized an appropriate molecular weight and calculates means modified, extended hard-sphere (EHS) that makes use universal function relating reduced volume. In this work we have also mixtures containing alkylbenzene cycloalkane species. Furthermore, new 3-component (3-cEHS) which requires only knowledge overall composition n-alkane, Extensive comparison with available experimental data indicates both models (1-cEHS 3-cEHS) binary multicomponent species uncertainty 5–10%. The proposed are precursor family do not require detailed mixture, but still take advantage underlying description.
