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

  • Algebraic models
  • Eddy viscosity transport models, one and two equation models
  • Non-linear eddy viscosity models and algebraic stress models
  • Reynolds stress transport models
  • Detached eddy simulations and other hybrid models
  • Large eddy simulations
  • Direct numerical simulations
