Interfacial destabilization and atomization driven by surface acoustic waves

  title={Interfacial destabilization and atomization driven by surface acoustic waves},
  author={Aisha Qi and Leslie Y. Yeo and James R. Friend},
Surface acoustic wave atomization is a rapid means for generating micron and submicron aerosol droplets. Little, however, is understood about the mechanisms by which these droplets form due to the complex hydrodynamic processes that occur across widely varying length and time scales. Through experiments, scaling theory, and simple numerical modeling, we elucidate the interfacial destabilization mechanisms that lead to droplet formation. Using a millimeter-order fluid drop exposed to surface… CONTINUE READING
