Abstract
The present contribution is dedicated to a numerical analysis of the dynamic behavior of near-field acoustic levitation, in the context for which an object is levitated due to forces generated by a pressure field produced by the vibration of a driving surface. For this purpose, per the existing literature, a fluid mechanical approach was used to model a simplified problem of a compression film between a driving surface and a levitated object.
