摘要：The influence of high frequency vibrations on the large volumes of fluids are not sufficiently studied, but the ultrasound separation of microparticles from liquid in microchannels is known technique. Acoustic standing wave technology creates new opportunities to improve advanced particle and cell separating systems. In this paper an interesting case of using the acoustic pressure method in the vertical plane is considered. The frequencies that were used lie below the threshold of the ultrasonic range and are unique in their structure. The case of interaction of a bimorph plate with a suspension is considered. The influence of the presence of a liquid on the change in the resonant frequencies and the effect of the exfoliation and transport of particles in the suspension are of interest.
