Turbulence modeling

Theory

• In this tutorial you find the basic theory of turbulence modeling.

• This tutorial gives a compact explanation of a laminar solver as well as a turbulent solver and the difference between them.

• Here you will find a basic 2D hands-on tutorial to understand the theory of steady-state turbulence modeling.

• Here you will find a basic 2D hands-on tutorial to understand the theory of transient turbulence modeling.

Application cases

The DrivAer case

Finally. This is a very cool case. Here you can test all the knowledge you gained so far by applying it in this case, where you will simulate the flow around a car. In particular, you will consider the following steps:

• meshing
  • blockMesh
  • snappyHexMesh
  • mesh quality
• turbulence modeling
• boundary conditions
• numerics
• functionObjects

Flow around a circular cylinder - 2D case

Let's start with the flow around a cylinder. With your knowledge gained yesterday, conduct this parameter study in order to gather experience about

• difference between a laminar and a turbulent flow
• case setup
• dictionaries
• output
• parameter study
• postprocessing

Flow around a square cylinder - 3D case

Now with the theory covered, go back and conduct a second parameter study about vortex shedding behind a square cylinder. With all the knowledge and experience, that you gained you should be able to correctly

• set up a case
• choose the correct
  • RAS models
  • LES models
• postprocess the results
