Abstract

Nanoparticles have been receiving attention in many fields such as electronic materials, medicine and so on. In this study, to generate nanoparticles for a chemical process, we have generated mono-disperse droplets in the flowing ambient liquid by using a torsional bolt-clamped Lngevin-type transducer and a micropore plate. When pure water was used as the dispersed liquid and n-dodecane solution was used as the ambient liquid, we have succeeded in generating mono-disperse droplets in the flowing ambient liquid productively. When the applied pressure of dispersed liquid and the vibrational velocity of the micropore were 0.13MPa and 96.5mm/s, the average diameter of generated droplets and the coefficient of variation were 51.3μm and 3.6, respectively.
