Effect of PZT driving waveform and frequency on meniscus shape and dropon-demand droplet formation parameters

Creator:

Yang, Guozhong

Abstract:

For piezoelectric stack (PZT) driven droplet generator, the driving waveform and driving frequency effect on liquid filament shape and droplet characteristics have been experimentally studied. The experimental study was based on a PZT driven droplet generator with known geometric design parameters and working fluid properties. A lumped-element-model (LEM) constructed to...
