Turbulence modeling is in several cases a very important topic in a simulation project. These tutorials explain, how you can utilize them in OpenFOAM.
Go back to Collection by topic.
Turbulence modeling
Theory
- Detailed theory on turbulence modeling - In this tutorial you find the basic theory of turbulence modeling.
- Steady-state turbulence modeling - Here you will find a basic 2D hands-on tutorial to understand the theory of steady-state turbulence modeling.
- Turbulence – Steady state - Use simpleFoam solver, run a steady state simulation with following turbulence models: kEpsilon (RAS), kOmega (RAS) and LRR (RAS).
- Transient turbulence modeling - Here you will find a basic 2D hands-on tutorial to understand the theory of transient turbulence modeling.
- Turbulence – Transient - Use the pisoFoam solver, run a backward facing step case for 0.2 s with different turbulence models: Smagorinsky (LES), kEqn (LES) and kEpsilon (RAS).
Application cases
- Flow around a circular cylinder - 2D case - This tutorial describes the flow around a 2D circular cylinder.
- Flow around a square cylinder - 3D case - This tutorial describes the flow around a 3D square cylinder.
- Flow around a hemisphere - This tutorial gives you an extensive introduction to the flow around a hemisphere, which can be seen as one of the simplest case of an external flow.
