Density and viscosity of biodiesel as a function of temperature: Empirical models

摘要

Biodiesel is a promising alternative of renewable energy obtained from natural raw material. This work presents empirical models to predict the density (p) and dynamic viscosity (μ) of fatty acid methyl esters (FAMEs), biodiesel, and biodiesel blends in a wide range of temperature. The average absolute deviation (AAD) was 0.43% in density, and 6.39% in viscosity.
