Prediction of the viscosity of multi-component liquid mixtures:: a generalized McAllister three-body interaction model

摘要: Abstract The work of Heric and Brewer (1969 Journal Chemical Engineering Data , 14 55–63) which involved testing a number liquid viscosity correlations resulted in concluding that the McAllister (1960 A.I.Ch.E. 6 427–431) model was most accurate. However, fact is correlative nature severely limits its practicality usefulness. This because costly time-consuming data are required for determination adjustable (or interaction) parameters contained (Asfour, Cooper, Wu & Zahran, 1991, Industrial Chemistry Research 13 1666–1669). study reports development generalized expression multi-component mixtures, evaluation parameters, converting into predictive model, comparison capability with those GC-UNIMOD reported by Cao, Knudsen, Fredenslund Rasmussen (1993a,b 32 2077–2087, 2088–2092) corresponding states principle (GCSP) Teja Rice (1981 Chemistry, Fundamentals 20 77–81). clearly indicated consistently far superior to GCSP predicting viscosities ternary, quaternary, quinary mixtures. This, no doubt, represents significant accomplishment area viscometric behaviour
