Mar 2, 2017 LRR: Launder, Reece and Rodi Reynolds-stress turbulence model for incompressible and compressible flows. LamBremhorstKE: Lam and Bremhorst low-Reynolds number k-epsilon turbulence model for incompressible flows; LaunderSharmaKE: Launder and Sharma low-Reynolds k-epsilon turbulence
with OpenFoam. Starting from a working laminar model. . . i. Change governing equations to include turbulence : Copy files fvSchemes and fvSolution from the /system sub-directory of a turbulent tutorial ,. e.g. /tutorials/incompressible/pisoFoam/ras/cavity/system, into your own /system directory. ii. Select turbulence model :.
The RAS turbulence model is selected by the RASModel entry from a long list of available models that are listed in Table A.5. . in the nut/mut file, the user should select epsilonWallFunction on corresponding patches in the epsilon field and kqRwallFunction on corresponding patches in the turbulent fields k, q and R.
Properties. Two equation model: turbulence kinetic energy, , and turbulence dissipation rate,; Extensively used with known performance; Over-prediction of turbulence kinetic energy at stagnation points; Requires near-wall treatment

May 26, 2012 has to be set in the mut / nut file according to what Alberto and the manual suggest (www.openfoam.org/docs/user/tu38-2090007.2.2). What sounds strange to me is that in the "0" directory, OpenFOAM calculates mut/nut depending on k, epsilon, omega or whatever (at least it writes mut down just
Properties. Model equations. The turbulence kinetic energy equation is given by: and the dissipation rate by: The turbulence viscosity is calculated using: where the is given by:

Properties. Two equation model for the turbulence kinetic energy, , and turbulence specific dissipation rate, . Aims to overcome the defficiencies of the standard k-omega model wrt dependency on the freestream values of k and omega; Able to capture flow separation; OpenFOAM variant is based on the 2003 model 
models (Spalart-Allmaras, k-epsilon, k-omega, k-omega-SST) by using the open source software. OpenFOAM. Particular attention will be given to the size of the recirculation bubble, By being open, OpenFOAM offers users complete freedom to customize and extend its existing doc: pdf and Doxygen documentation;.
