摘要

The evaporation flux and the lifetime of nonventilated droplets of multicomponent liquids depend on their physical-chemical properties and the ambient parameters. This work proposes reliable estimation methods, which can be used for the prediction of key input parameters of quasiequilibrium evaporation models in the lack of correct experimental data. The importance of the selection of appropriate activity coefficient and diffusion/convection models is discussed. A special coupling of computational fluid dynamics (CFD) simulation and solvation mixture thermodynamics using COSMO-RS theory for liquid−vapor equilibrium and gas-phase transport characteristics of components of evaporating real liquid mixtures is highlighted.
