Acoustic Levitation - A Novel Alternative to Traditional Lubrication of Contacting Surfaces

Tribology Online, 2014
Fundamental aspects and mechanisms of acoustic levitation together with governing equations are presented first. Then, the acoustic levitation phenomenon is considered as a new way to design air suspension systems capable of self-levitation. A particular
