Additional information (links, pictures, etc.)

This test-case is dedicated to the verification of the rough law-of-the wall, with different roughness (in meters).

As it can be seen in all the figures, the results are in good agreement with the experiment either for the smooth-to-rough transition or the rough-to-smooth transition.

Each curve on the two graphs herebelow represents a velocity profile at a given distance (in meters) from the transition.

  • Smooth-rough velocity:

  • Rough-smooth velocity:

  • Smooth-rough surface stress:

  • Rough-smooth surface stress:
