Particle size of non-contact atomization of low surface tension liquid by powerful aerial ultrasonic

Recently, there is a growing demand for atomizing techniques of chemical or production line. The non-contact atomizer is used for atomization part of the mass spectrometer. However, atomization characteristics have not been revealed. Therefore, it is performed a study to reveal the atomization characteristics. To determine the atomization properties of the ultrasonic source, we examined the sound pressure distribution of the standing wave acoustic field formed and observed the behavior of the atomized particles in the acoustic field. Further, Sample liquid is water, ethanol and glycerin were examined the particle diameter of varying electric input power. The average particle number depended on the mass of the liquid, and the median particle diameter did not depend on the input power. The measured median particle diameter was similar to the value calculated by Lang´s equation.
