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

气泡或粒子被困在声音驻波节点处的现象被广泛地称为声悬浮。由于声功率可以使物体非接触地悬浮和移动，因此，这种声悬浮技术在半导体、航空航天和生物工业中具有巨大的应用潜力。本研究项目为管内净化分级系统的设计与开发可行性研究，探索仅靠声功率驱动非接触细颗粒并进行分级的可能性。

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.
