Default Free air turbulence properties

Hi again!

I'm simulating a 2d airship envelope in free air and I have problems with the results I get(I'm used to simulate pipes and i'm affraid I'm setting wrong some parameters).

I put muy envelope model into a circle and I define the circle line as velocity inlet. I choose in fluent K-epsilon as viscous model. When I set the v_inlet paramentes I don't know what to write in order to model free air.

Can anyone help me with those properties for free air?

Turbulet kinetic energy and turbulent dissipation rate or Turbulence intensity and turbulence length scale or Turbulence intensity and turbulence viscosity ratio

Thanks very much!!!

Luis
