Low-frequency acoustic atomization with oscillatory flow around micropillars in a microfluidic device

This letter reports a low frequency acoustic atomization technique with oscillatory extensional flow around micropillars. Large droplets passing through two micropillars are elongated. Small droplets are then produced through the pinch-off process at the spindle-shape ends. As the actuation frequenc...
