The superordinate objective of this research project proposal is the development of efficient models and methods for the calculation of turbulent multicomponent spray flames under subcritical conditions. Focus is given on the use of the large eddy simulation (LES) approach coupled with the method of reduction of chemical mechanisms FGM. Special attention will be given to mixtures of ethanol and water, in view of the strategic importance that anhydrous and hydrous ethanol have for Brazil. According to the characteristics of this mix, several challenges are expected. Specifically, added to the non-ideal behavior of ethanol and water mixtures, the fact that ethanol is a fuel and water is a combustion product indicates that interferences must occur in the mixture preparation and oxidation regions of combustion processes. In summary, investigations will focus on the characterization of mixture stratification, multicomponent droplet evaporation, and flame-turbulence and droplet-flame interactions.
