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.
