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
• Large eddy simulations
• Detached eddy simulations and other hybrid models
• Direct numerical simulations
