Default k and epsilon

Dear users,

I'm working with a simulation of external aerodynamics relating to a truck. How do I specify k and epsilon at boundary of a wind tunnel chamber with turbulence intensity I=0.2%?

Thanks.

This is very easy, especially if you have the turbulence intensity, just go to the help menu and under the k-e model you will find two formulas that you can use to do this.

Yes, I know what you mean but k is a funcion of I (I:intensity) and epsilon is a function of (mu-t/mu). The ratio mu-t/mu is between 10 and 100. So how can I estimate the value? Can you do an example?

Davide.
