OpenFOAM is distributed with a huge library of turbulence models as listed below.

The open architecture of OpenFOAM allows developers to add turbulence models easily that can be selected a run time by the user.

Turbulence models for incompressible fluids
laminar	Dummy turbulence model for laminar flow
kEpsilon	Standard model with wall functions
RNGkEpsilon	RNG model with wall functions
NonlinearKEShih	Non-linear Shih model with wall functions
LienCubicKE	Lien cubic model with wall functions
QZeta	model
LaunderSharmaKE	Launder-Sharma low- model
LamBremhorstKE	Lam-Bremhorst low- model
LienCubicKELowRE	Lien cubic low- model
LienLeschzinerLowRE	Lien-Leschziner low- model
LRR	Launder-Reece-Rodi RSTM with wall functions
LaunderGibsonRSTM	Launder-Gibson RSTM with wall-reflection terms and wall functions
SpalartAllmaras	Spalart-Allmaras 1-eqn mixing-length model for external flows
