On the Viscosity of Ternary Mixtures.

Abstract

A modified form of an equation developed earlier by Katti and Chaudhri for binary systems Is proposed for the representation of viscosity In ternary mixtures. Results by this approach are compared with experimental data and with results predicted by use of the more complex equation of Kalidas and Laddha. The present approach Is correlated with the experimental data equally as well as Is that of Kalidas and Laddha. ACCURATE analytical viscosity-concentration functionsare essential to a solution of fluid flow problems in multicomponent systems. In addition, for purposes of theoretical interpretation, it is desirable that such equations include separately contributions from ideal mixing and terms that arise from

Excess molar volumes and dynamic viscosities for binary mixtures of toluene+n-alkanes (C5–C10) at T=298.15K – Comparison with Prigogine–Flory–Patterson theory

“…This work will also provide a test of various semi-empirical equations to correlate viscosity of binary mixtures. The types of used relations are Grunberg and Nissan [13], Tamura and Kurata [14], Hind et al [15], Katti and Chaudhri [16], McAllister [17], Heric [18], and Kendall and Monroe [19].…”

Excess molar volumes, viscosities, and speeds of sound of the ternary mixture {1-heptanol (1)+trichloroethylene (2)+methylcyclohexane (3)} at T=298.15K

“…The best correlation method for the ternary system was found using the Nagata equation. The viscosity data for the binary and ternary mixtures were fitted to Nissan and Grunberg [10][11][12], Hind et al [11][12][13][14], Katti and Chaudhri [11,12,15], McAllister [11,12,16], Heric [11,12,17], Frenkel [11,12,18], and Iulan et al [11,12,19] and their parameters have been calculated. Theoretical models dealing with liquid state including Jacobson free length theory (FLT) [20][21][22][23], Schaaff collision factor theory (CFT) [21,23,24], Nomoto relation (NR) [21,25], Junjie relation (JR) [21,26] and Van Deal ideal mixing relation (IMR) [21,27] have been proposed for the prediction of the speeds of sound and isentropic compressibilities of the binary and ternary mixtures.…”

Ultrasonic Studies in Binary Liquid Mixtures Oftrichloroethylene With Three Alcohols at 303.15 K

“…[1][2][3][4][5] Knowledge of density and viscosity is important in designing the processes involving chemical separations, equipment design, solution theory, heat transfer, fluid flow and molecular dynamics. The research findings [6][7][8][9][10] proved that the data on viscosity are useful for testing the theories and empirical relations of liquid mixtures. The study of the ultrasonic velocity in liquids and liquid mixtures and its influence on molecular structure were studied by several researchers.…”
