Design of Single-Axis Acoustic Levitators

  • Marco A. B. AndradeEmail author


In this chapter, a numerical procedure based on the finite element method (FEM) is presented for simulating and designing single-axis acoustic levitators. We first present an overview of the equations governing the propagation of mechanical waves in solids, piezoelectric materials and the air medium. We then show how axisymmetric models based on FEM can be utilized for simulating piezoelectric transducers and the acoustic cavity of the levitator. To illustrate the design procedure, the finite element method is applied to simulate and design a 25-kHz bolt-clamped Langevin-type transducer. The FEM is also used to design a resonant single-axis acoustic levitator and to investigate the behavior of a non-resonant acoustic levitator.
