“…In liquids, a variety of empirical models have been proposed to predict the temperature dependency of liquid viscosity. A common prediction of these models is that the viscosity of a liquid follows an exponential or Arrhenius-like decay by increasing temperature [18,20].…”

“…Therefore, K and n are determined experimentally from isothermal viscosity and shear rate data. Equation 1 often can be used to describe the rheology of non-Newtonian fluids and provides a simple model for this behavior when compared to other, more complex models such as those proposed by Lang et al (4) and Toro-Vazquez and Infante-Guerrero (5), which have been used in the past to predict viscosity with high accuracy.…”

The rheological properties of yellow grease and poultry fat and their liquid density at 25.0°C were experimentally determined. Dynamic viscosities of these industrial recycled fat products were measured for shear rates of 0.65 to 32.34 s −1 at temperatures of 15.6 to 71.1°C. The resulting measurements were fitted to a power law model to obtain values for the consistency coefficient and the flow behavior index. The data was also fit to Andrade's equation to relate viscosity to temperature. These results indicated pseudoplastic flow behavior for both products, with increasing non-Newtonian behavior at higher temperatures and shear rates.Paper no. J10083 in JAOCS 79, 961-964 (October 2002). KEY WORDS:Biodiesel, chicken fat, fatty acids, poultry fat, recycled fats, rheology, shear rate, triglycerides, viscosity, yellow grease.where D and B are empirical constants and T is absolute temperature (6). This analysis is performed by measuring viscosity changes with varying temperature at a constant shear rate.

“…However, there is a dearth of information on the effect of temperature on the viscosity and density of binary and ternary blends of biodiesel oil. Modelling of the temperature effect on the dynamic viscosity of oils is important and has been investigated by some researchers [25,[27][28][29]. However, modelling of the effect of temperature on viscosity and density of biodiesel is rarely reported.…”

The depletion of world petroleum reserves and the increased environmental concerns have stimulated the search for alternative sources for petroleum based fuel. The possibility of using vegetable oils as fuel has been recognized, however, due to its high viscosities and low volatilities makes it inefficient for most combustion engines and thus the need to get them chemically altered or transesterified to obtain fatty alkyl esters of the oil (biodiesel). In this study, binary and ternary blends of biodiesel were produced and the effect of temperature on their viscosity and density was investigated. Biodiesel was produced from soybean oil by transesterification of the oil with methanol using potassium hydroxide as a catalyst at a temperature of 60˚C in a batch reactor. Binary and ternary blends of the soy-biodiesel were prepared with soy bean oil and petroleum diesel fuel, respectively. Viscosities and densities of the binary and ternary blends were measured at different temperatures of 20˚C to 90˚C as to determine the effect of temperature on viscosities and densities of the blends. The properties of the soy-biodiesel produced were compared with ASTM standard and found to be within the limits. The results show that the viscosities and densities of both the binary and ternary blends are temperature dependent. The viscosities of binary and ternary blends decreased nonlinearly with temperature, while their densities decreased linearly with temperature. The variation of temperature with viscosity and density of the blends was correlated and the polynomial equation offered the best correlation between temperature and viscosity, while linear equation gave the best correlation between temperature and density. In conclusion, the efficiency of binary and ternary blends of biodiesel in combustion engines is dependent on the viscosity and density of the blends which are invariably temperature dependent.
