Abstract

In recent years, a generation of emulsions has been experimentally investigated. In this study, to generate high-quality W/O (Water-in-Oil) emulsions, we have designed a droplet generation system using a torsional bolt-clamped Langevin-type transducer and a micropore plate, and generated droplets in the flowing continuous liquid directly and successively. When the vibrational velocity of micropore and the applied pressure of dispersed liquid were 96.5 mmls and 0.140 MPaG, the average diameter of generated droplets and the standard deviation were 62.5 um and 2.6 um, respectively. In addition, we have found a transition point in which generated droplets became uniform in the flowing continuous liquid, and we have succeed in generating droplets with wider pressure range into the flowing continuous liquid compared with the generation into the continuous liquid.
