The interest in biofuels was stimulated by the fossil fuel depletion and global\nwarming. This work focuses on the impact of biodiesel fuel on ethanol/diesel (ED) fuel blends.\nThe soybean methyl ester was used as a representative composition of typical biodiesel fuels.\nThe heating and evaporation of ethanol-biodiesel-diesel (EBD) blends were investigated using the\nDiscrete-Component (DC) model. The Cetane Number (CN) of the EBD blends was predicted based\non the individual hydrocarbon contributions in the mixture. The mixture viscosity was predicted using\nthe Universal Quasi-Chemical Functional group Activity Coefficients and Viscosity (UNIFAC-VISCO)\nmethod, and the lower heating value of the mixture was predicted based on the volume fractions and\ndensity of species and blends. Results revealed that a mixture of up to 15% biodiesel, 5% ethanol, and\n80% diesel fuels had led to small variations in droplet lifetime, CN, viscosity, and heating value of\npure diesel, with less than 1.2%, 0.2%, 2%, and 2.2% reduction in those values, respectively.
