High frequency thickness mode ultrasound is an energy-efficient way to atomize high-viscosity fluid at high flow rate into fine aerosol mists of micron-sized droplet distributions. However the complex physics of the atomization process is not well understood. It is found that with low power the droplet vibrates at low frequency (O (102) Hz) when driven by high-frequency ultrasound (O (106) Hz and above). To study the mechanism of the energy transfer that spans these vastly different timescales…
