Stokes Boundary Layer

Problem Discription

All files can be downloaded here

In this tutorial we will have a look at the stokes problem, where we use the LinFlow-PDE to solve this problem. The bottom is excited with a velocity which creates a flow inside the fluid. Depending on the frequency the boundary layer changes.

Here a good illustration from wikipedia:

Tutorial Suggestions

• Run the simulation
• Try to visualize the velocity field in paraview (How to visualize field results and see how the field oszilates for different frequencies (How to animate harmonic results)
• Try to visualize the velocity over the boundary layer thickness for the different frequency steps, using python.

Coupling to other fields

You can couple the linFlow-PDE to various fields. For example's look into our testsuite:

• Coupling to the Acoustic field
• Coupling to the Mechanic field
• Coupling to the Thermal field
