A06 超音波霧化に及ぼす溶媒種の影響(口頭発表)

抄録

Ultrasonic atomization is a very effective way to generate fine droplets. However, it is difficult to measure the atomization rate because the evaporation occurs at the same time. In this study, the atomization rate was estimated and the effect of frequency and solvent properties on droplet generation was investigated. An ultrasonic transducer was installed at the center of the vessel bottom. In order to produce fountain jet without ultrasound, the pump and nozzle were used. It is defined that the difference of mass changes between ultrasound and liquid pump is the atomization rate. The atomization rate increases with decreasing surface tension and viscosity of solvent. The droplet generates after the fountain appears. The number of droplet for 2.4 MHz is higher than for 0.5 MHz.
