Feasibility study on in-tube decontamination system driven by non-contact acoustic levitation

气泡或颗粒被捕获在声音驻波的节点位置的现象被广泛称为声悬浮。 由于声悬浮技术可以使物体在声力的作用下非接触地悬浮和移动，因此在半导体、航空航天和生物工业中具有巨大的应用潜力。本研究项目是关于设计和开发管内净化和分类系统的可行性研究，探索仅用声功率非接触驱动细颗粒分级的可能性。

Phenomenon that bubbles or particles are trapped at the position of the node of the standing wave of sound is widely known as acoustic levitation. As objects are possible to be levitated and moved with non-contact by the sound power, therefore, this acoustic levitation technique has a huge potential in applications for semiconductor, aerospace and biology industries.This research project is a feasibility study on design and development of an in-tube decontamination and classification system, and to explore the possibility to drive and classify fine particles with non-contact by the sound power only.
