摘要
The three parameter and shape factor corresponding states principle (CSP) are used respectively to predict the shear viscosities of LNG mixtures successfully.In the three parameter CSP calculation,only one adjustable interaction coefficient is required to characterize each binary system.When this coefficient is set as a unity,the three parameter CSP gives nearly the same extent of accuracy as the shape factor CSP,with the average absolute deviation between the calculated and experimental data ranging from 2% to 9%.However,when an optimized coefficient is introduced to the three parameter CSP,it may result in very accurate predictions,well within the accuracy of the experimental data with the deviation less than 3%.It is also found that the accuracy of the shape factor approach shows a tendency that the deviation increases with the increase of the densities of the LNG mixtures.
