Abstract :
In the present study, double waveforms to drive a piezoelectric inkjet nozzle have been applied to the droplet formation of low viscosity liquid. The effect of the driving voltage and time separation between the pulses was observed. Even though several satellites are produced in the single waveform, the droplet formation could be precisely controlled in the double waveform. The shorter is the time separation, the smaller droplet is formed. The main effect of double waveform is that the second pulse reduces the mass and momentum of the ejected liquid.
