Two new models for viscosity prediction of binary, ternary and higher order liquid mixtures

Abstract

Viscosity, a key transport property, plays a pivotal role in chemical and petroleum industries due to its application related to flow measurements. Two new equations have been proposed for prediction of the viscosity of binary, ternary and multicomponent liquid mixtures. The predictive capabilities of the proposed models have been validated against some well established relations by putting them to the test in 188 binary, 25 ternary, 5 quaternary, 1 quinary and 3 hexanary systems at varying temperatures. A comparative study has been carried out by taking absolute average percentage deviation as the criterion. The results indicate that both the proposed models are capable of predicting viscosity better than most of the well established relations exhibiting remarkable predictive capability.
