Hi,

The standard k-omega - model which incorporates modifications for low-Reynolds number effects. The low-Reynolds number terms can produce a delayed onset of the turbulent wall boundary layer and constitute therefore a very simple model for laminar-turbulent transition. In general, the use of the low-Reynolds number terms in the k- models is not recommended, and it is advised to use the more sophisticated, and more widely calibrated, models for laminar-turbulent transition instead. So I suggest please have a look at the reynolds number in your case.
