Vibrating Plate in a 2D Viscous Parallel Plate Flow
Application ID: 18871
This is a small 2D demonstration model that couples the Linearized Navier-Stokes, Frequency Domain, Solid Mechanics, and Creeping Flow physics interfaces to model the vibrations of a plate located in a 2D viscous parallel plate flow.
This type of model is used to model fluid-structure interaction (FSI) in the frequency domain.
For simplicity, the flow is assumed to be a creeping flow. At the inlet and outlet of the channel, a perfectly matched layer (PML) is added. Extrusion operators are used to couple the flow to the acoustics problem in these domains.

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. To determine the right combination of products for your modeling needs, review the 製品仕様一覧 and make use of a free evaluation license.
