Abstract

The present work deals with the evaporation of acoustically levitated droplets. It was shown before by the authors that droplets of pure liquids in acoustic levitators evaporate mostly due to the convective effect of the acoustic streaming arising near the free droplet surface. In the present work acoustically levitated droplets of binary liquid mixtures are considered. The theoretical model of acoustically driven droplet evaporation, as developed in an earlier publication of the authors, is extended for these liquids, and experimental investigations on the evaporation of droplets consisting of the liquids are conducted. Results from theory and experiment are compared and discussed.
