“…Viscosity deviation (Δviscosity) is the difference between the measured value and an “ideal value”: The ideal viscosity can be based on either kinematic viscosity, dynamic viscosity, or natural logarithms of these values. ,,− The instrument used in this study measures dynamic viscosity, so ideal viscosities (η ideal ) were calculated by ,,,,,, or from where η 1 , η 2 , and η 3 are the dynamic viscosities of the pure components, and x 1 , x 2 , and x 3 are their mole fractions with the aromatic compound as component 1, n- butylcyclohexane as component 2, and the n- alkane as component 3. The viscosity deviations calculated using eqs – have been related to the strength of intermolecular interactions between mixing components, , and Grunberg and Nissan included an extra term in their prediction of viscosity in a 2-component system (η mix ) to account for these interactions: where d is the “characteristic constant of the system.”…”

Researchers seek to understand the combustion of petroleum fuel, which contains hundreds of compounds, by studying properties and oxidation behavior of less complex mixtures (surrogates) containing fuel components. In this study, viscosities and densities (293.15 to 343.15 K), speeds of sound (293.15 to 333.15 K), surface tensions (∼314 K) and flash points were measured for ternary mixtures of representative fuel components: n-alkanes, aromatic compounds, and n-butylcyclohexane. Mixture surface tensions and flashpoints fell between the pure component values. The speeds of sound for ternary mixtures containing n-dodecane and n-butylcyclohexane increased with increasing aromatic compound concentration. As the aromatic compound concentration in mixtures with n--hexadecane and n--butylcyclohexane increased, the mixtures' speeds of sound remained level or decreased to a minimum before increasing to the value of the aromatic compound. The isentropic bulk moduli increased with increasing aromatic compound concentration, except for toluene for which a minimum was found. Excess molar volumes were positive, viscosity deviations were negative, and a McAllister three-body equation successfully modeled viscosity. Positive excess molar volumes and negative dynamic viscosities suggest that dispersion forces dominate the molecular interactions in these mixtures.

“…Hence, it becomes of considerable interest to compute viscosity in liquid mixtures by applying various mathematical models and to identify the suitable relation for the studied liquid mixtures. As a continuation of our effort [11,12], dynamic viscosities of binary system: Tri-n-butyl phosphate (TBP) + benzene are estimated by using different mathematical relations of zero, one and two adjustable parameters [13][14][15][16][17][18][19][20][21] at 308.15K and then comparing the computed values of viscosities with that of the experimentally measured values. Our survey of the literature shows that there have not been any theoretical viscosity data reported for the binary system of TBP with benzene.…”

Dynamic viscosities () of a binary liquid system: Tri-n-butyl phosphate (TBP) + benzene have been experimentally measured over the entire range (X1) of TBP at temperature 308.15K and pressure 0.1MPa. The dynamic viscosity of liquid mixtures hasbeen calculated using five mathematical relations of zero adjustable parameters such as Croenaurer-Rothfus- Kermore relation, Gambrill relation, Bingham relation, Kendall-Munroe relation and Arrhenius – Eyring relation. The validity of these relations has been verified separately by taking the average percentage deviations (APD) and root mean square deviation relative (RMSDs) between experimental and computed values and displayed graphically. Furthermore, the mixture viscosities have been correlated with those predicted one by using another six models of single and double adjustable / interaction parameters such as Grunberg-Nissan, Katti and Chaudhri, Hind, Tamura -Kurata, Heric and Eyring-Margules. A comparison between theoretical and experimental values of viscosity divulges that Gambrill’s relation predicts the data reasonably well in case of zero adjustable parameters whereas Eyring-Margules shows the best fit in case of single and double interaction parameters.

“…The viscosities of the quaternary mixtures are given in Table . The dynamic viscosity deviation, Δη, is the difference between the value measured for the mixture, η mix , and an ideal value, η ideal . The ideal value has been defined in different ways by different authors − as in which η 1 , η 2 , η 3 , and η 4 are the pure component dynamic viscosities, and x 1 , x 2 , x 3 , and x 4 are the mole fractions of the n -dodecane, n -butylcyclohexane, n -butylbenzene, and isocetane as components 1, 2, 3, and 4, respectively. The dynamic viscosity deviation was calculated using both eqs and .…”

The composition of Navy Jet fuel JP-5 was determined using gas chromatography(GC)-electron impact mass spectrometry and GC × GC/(flame ionization detection) to contain by mass 21% linear alkanes, 29% cycloalkanes, 32% isoalkanes, and 18% aromatic compounds. Various quaternary mixtures of n-dodecane, n-butylcyclohexane, n-butylbenzene, and 2,2,4,4,6,8,8-heptamethylnonane were prepared as possible surrogates for this jet fuel and analyzed for density and viscosity (253 to 333) K, speed of sound (288 to 333) K, surface tension (294 ± 1 K), and flashpoint. Deviation cutoffs for “matching” the JP-5 based on previous studies and fuel specification were ±1.7% for density, ±1% for speed of sound, ±3.5% for bulk modulus, ±2.6% for viscosity, ±2.2% for surface tension, and ±10% for flash point (minimum of 333 K). Seven quaternary mixtures met these cutoffs. Three had compositions that were comparable to the JP-5 and would be good candidates for engine testing. All mixture excess molar volumes showed a trend of increasing to a maximum and then decreasing as the concentration of n-butylbenzene increased. Viscosity deviations ranged from (−0.03 to −0.48) mPa·s.
