3D Acoustic Trap and Thermoacoustic Streaming in Glass Capillary

Application ID: 105991

A 3D model of an acoustic trap in a glass capillary actuated by a piezoelectric transducer. The system is actuated by an oscillating electric potential across the piezoelectric transducer inducing mechanical vibrations in the solid and an acoustic pressure field in the fluid. The heat from the piezoelectric transducer is modeled which creates a temperature gradient in the glass capillary causing gradients in the fluid properties. The acoustic field and the gradients in the fluid properties induce thermoacoustic streaming which creates four big streaming rolls. Lastly, the trajectories of glass and polystyrene particles are modeled with the Particle Tracking interface.

This model example illustrates applications of this type that would nominally be built using the following products:
