oscillation of vortex in a breaking droplet is observed. The droplet size is dependent on the flow-rate
combination of the two fluids as well as the frequency and power of the acoustic actuation. Acoustic
microstreaming flow is observed in the dispersed phase at the cross-junction of the device. The
microstreaming flow causes a stratified vortex flow structure within the dispersed phase. Two
stratified vortex centers at the side poles of the droplet are found.详细>
