3D Acoustic Trap and Thermoacoustic Streaming in a 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:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- Acoustics Module and
- CAD Import Module and
- Particle Tracing Module and
- either the Battery Design Module, CFD Module, Chemical Reaction Engineering Module, Corrosion Module, Electrochemistry Module, Electrodeposition Module, Fuel Cell & Electrolyzer Module, Microfluidics Module, Polymer Flow Module, Porous Media Flow Module, or Subsurface Flow Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products.
