As defined by Wikipedia:

Turbulence modelingis the construction and use of a model to predict the effects of turbulence. Averaging is often used to simplify the solution of the governing equations of turbulence, but models are needed to represent scales of the flow that are not resolved.

~~ Here~~ J.~~ is~~ Blazek~~ shown~~ has described how common models relate to each other:

Level | |
---|---|

Level 0 | Direct Numerical simulation (DNS) |

Level 1 | Large-Eddy Simulation (LES) |

Level 2 | Reynolds-Averaged Navier-Stokes equations |

2nd order (closures). Reynolds-Stress Transport models (RST) | |

2nd order. Algebraic Reynolds Stress models (ARS) | |

Level 3 | 1st order (closures) |
