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
Rearward facing step
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
