Abstract

In this study, a torsional bolt-clamped Langevin-type has been used for generating micro droplets. A plate had a micropore and was attached at the tip of the was oscillated by the transducer. By using torsional , many micropores can be oscillated uniformly. When micropore plate was not oscillated, droplets were generated . On the contrary, when a micropore plate was, droplets were generated regularly. When the pore , the vibrational amplitude and the resonance frequency 16m, 0.62mp-p and 56 kHz, respectively, the averaged of droplets was 26.8m. The standard deviation of the was 1.41. In addition, by using this transducer, W/O (Water-in-Oil) emulsions were generated in air-liquid phase. the same condition, the averaged diameter of emulsion 35.0m, the standard deviation was 1.9 and the coefficient ofwas 5.5.
