Acoustic Streaming in a Microchannel with Inhomogeneous Fluids
Application ID: 121501
In acoustofluidics, acoustics is used to manipulate particles and fluids in microfluidic devices. This model demonstrates the phenomena of the inhomogeneous acoustic body force and how it can move a fluid with an inhomogeneous density due to a solute.
The model is of a 2D rectangular cross section of a long rectangular microchannel and inspired by Ref 1. Where it is demonstrated that an acoustic field can move a high density fluid from the bottom to the center of a microfluidic channel. In the model Transport of Diluted Species is used together with user defined material parameters (Ref 1) that depend on the concentration of the diluted species.

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:
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.
