turbulentProperties
The current dictionary act as the selector for the turbulence model. Consequent quanitie must be updated or introduced given the model you of turbulence you want to solve.
RANS model (Reynolds Average Navier Stokes)
Usually three models are used and they can be specified in this way on constant/turbulenceProperties:

RASModel kOmegaSST; // or kEpsilon, kOmega, etc
