Correlation of the liquid mixture viscosities

Abstract

In this paper, forty-two selected correlation models for liquid mixture viscosities of organic compounds were tested on 219 binary and 41 ternary sets of experimental data taken from the literature. The binary sets contained 3675 experimental data points for 70 different compounds. The ternary sets contained 2879 experimental data points for 29 different compounds. The Heric I, Heric-Brewer II, and Krishnan-Laddha models demonstrated the best correlative characteristics for the binary mixtures (overall absolute average deviation lt 2 %). The Heric I, Heric-Brewer II, Krishnan-Laddha and Heric II models demonstrated the best correlative characteristics for the ternary mixtures (overall absolute average deviation lt 3%).

U ovom radu testirana su 42 odabrana modela za korelisanje viskoziteta tečnih smeša na literaturnim eksperimentalnim podacima za 219 binarnih i 41 ternernu smešu. Binarni setovi imaju 3675 eksperimentalnih podataka za 70 različitih supstanci, a ternerni 2879 eksperimentalnih podataka za 29 različitih supstanci. Heric I, Heric-Brewer II i Krishnan-Laddha modeli pokazali su najbolje korelacione osobine sa ukupnom srednjom procentualnom greškom manjom od 2 % za binarne smeše. Heric I, Heric-Brewer II, Krishnan-Laddha i Heric II modeli pokazali su najbolje korelacione osobine sa ukupnom srednjom procentualnom greškom manjom od 3 % za ternerne smeše.
