Abstract

Using ultrasonic waves to levitate particles is ultrasonic levitation, and it has potential applications in various fields such as micromaterial handling, medicine, and material characterization. For many of these applications, the behavior of the levitated particles during the levitation time is critical, including movements of the particle at a levitated point. Electrical potential and the distance between the transducer and reflector are two main parameters affecting the movement of the levitated particles. In this paper, a second-order linear model considering the effect of these parameters was presented to predict particle movement based on numerical results. In the modeling part, a 2D COMSOL dimensional axis-symmetric finite element model has been used to simulate ultrasonic levitation. Experimental tests have been performed and used to validate the model. The results in this report could help to understand the main factors in the movement of the levitated particle and develop methodologies for particle stabilization.
