Multicomponent vaporization modeling of bio-oil and its mixtures with other fuels

► Bio-oil drop size history does not follow the conventional D2-curve due to its complex composition. ► At the end of vaporization, only levoglucosan remains in the bio-oil drop. ► Vapor distribution of bio-oil spray is consistent with the volatilities of individual components. ► The presence of bio-oil in the mixture of bio-oil and other fuels extends the drop lifetime. ► The lifetime of pure bio-oil drops is relatively longer than diesel, biodiesel, and ethanol.
