Abstract

Kinematic viscosity of biodiesel blends is investigated theoretically. We employed a new method to estimate the
kinematic viscosity of biodiesel blends as a simultaneous function of temperature (T) and volume percent of
blend components. The correlation parameters determined using the new method represent the rate of variation
and behavior of kinematic viscosity with change in temperature and volume percent of blend. Different blend
systems are considered to illustrate the prediction accuracy of the method. The detailed analysis of the estimated
values and results revealed that the kinematic viscosity of biodiesel blends shows the characteristics temperature
dependence of 1/T2 rather than 1/T.
