Collection of turbulence modeling

Turbulence modeling is in several cases a very important topic in a simulation project. These tutorials explain, how you can utilize them in OpenFOAM.

Turbulence modeling

Theory

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

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

• Turbulence – Steady state - Use simpleFoam solver, run a steady state simulation with following turbulence models: kEpsilon (RAS), kOmega (RAS) and LRR (RAS).

• 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

• Transonic flow around a periodically pitching NACA0012 airfoil - In this tutorial you will learn about the compressible transonic flow around a periodically pitching NACA0012 airfoil including the study of differrent turbulence models
