Turbulence modeling is a key issue in most CFD simulations. Virtually all engineering applications are turbulent and hence require a turbulence model.
Classes of turbulence models
- RANS-based models
- Linear eddy-viscosity models
- Algebraic models
- One and two equation models
- Non-linear eddy viscosity models and algebraic stress models
- Reynolds stress transport models
- Linear eddy-viscosity models
- Large eddy simulations
- Detached eddy simulations and other hybrid models
- Direct numerical simulations
