A recently developed model for heating and evaporation of multi-component droplets, taking into account the effects of temperature gradient, recirculation and species diffusion inside them is described. The model is applied to the analysis of biodiesel droplets. The predictions of this model are compared with the predictions of the model based on the approximation of biodiesel fuel by a single component. Five types of biodiesel fuels are considered: Palm Methyl Ester, produced from palm seed oil; Hemp Methyl Esters, produced from hemp seed oil in the Ukraine and the European Union; Rapeseed oil Methyl Ester, produced from rapeseed oil in the Ukraine; and Soybean oil Methyl Ester, produced from soybean oil. It is shown that a simplistic model, based on the approximation of biodiesel by one component, leads to errors in predicted droplet evaporation times and surface temperatures of up to 5.5% and 2.4%, respectively.
