Generally, the atomization condition is dominated by the Weber number. In this research, we have fabricated the torsional transducer and longitudinal transducer to evaluate the effect of the atomization by the Weber number. We have observed the spray angle and atomization condition. First, to evaluate the performance of the spraying nozzle with the torsional vibration, water has been sprayed. When the driving frequency, the applied voltage, and the flow rate were 18.3 kHz, 100 Vp-p, and 15 ml/min, the water has been successfully atomized. In addition, although the ethylene glycol has higher viscosity, we have succeeded in atomizing ethylene glycol effectively. As a result, the torsional vibration is suitable for the atomization in a low flow rate.
