Concentric Cylinders-Couette Flow

Couette flow between two circular cylinders is used to investigate the behaviour of velocity boundary condition for complex geometries with q-values. In this flow, the inner cylinder with radius rotates with a constant angular velocity and the outer cylinder with radius is kept stationary.

This Couette flow has the following analytical solution where and .

The mesh created here is single level with 32 elements in inner cylinder diameter.

In these test cases, in addition to the aforementioned features, you will also learn how to:

  • Create a mesh with boundaries with q-values using Seeder.
  • Post-processing nd visualization in Paraview.
  • Create a 2D plot using Gleaner tool. Gleaner is a Python tool which extracts data from Musubi ascii output and uses matplotlib in python library to create a plot.
