Default k-epsilon model/turbulent intensity

Has anyone had any success with the k-epsilon model working for small values of turbulence intensity 5% and a turbulent ratio of 10 at the inlet??? It is my understanding that it is general practice to use these values.

I want to know because I'm simulating a wind tunnel experiment where the inlet turbulent intensity is about 0.5% - 1%.

Thanks so much, Erika

So would you not recommend using the standard k-epsilon model if your freestream turbulence is very small??? Does it not work well in those situations???
