Turbulence models available in Code_Saturne

The %$k - \varepsilon$% model

Two equation model for use with wall functions. Two versions available, the standard and the Production Limited.

The %$\varphi-f$% model

This is Low-Reynolds model that solves three transport equations and one elliptic equation to take into account the near wall effects where the log-law is not applicable.

Shear Stress Transport (SST)

A model that combines %$k - \varepsilon$% and %$k - \omega$% and limits the turbulent viscosity using a function based on the wall distance and the strain rate.

Other models not available on the official release

This models have been developed by researches and are not on the official release of Code_Saturne and therefore have not been extensively validated.

The BL-%$\overline{v^2}/k$% model

See here for details -

The Elliptic Blending Model

The Elliptic Blending Model (EBM) developed by Manceau and Hanjalic (2002) has been implemeted in v1.4.0. For details see here

Hybrid RANS-LES two velocity fields.

A model that combines LES and RANS by using two different turbulent viscocities based on two velocity fields, one instantaneous and one averaged. See here for more details.
