turbulence amounts for wind turbibne

niloogh · May 14, 2013, 06:18

hi
I'm simulating a wind turbine and wind tunnel around it in fluent
I had chosen k-w model for turbulence
but i don't know which kind of information in boundary condition is suitable(intensity and ratio or ...)
also i don't know which amounts are suitable for turbulence ratio and intensity
would you plz help me?

Don't change turbulence parameters unless you are trying to reproduce results of some wind tunnel tests whose turbulence parameters are given to you.

tnx dear far but I don't have any parameters and when i use default amounts of fluent my residuals don't Converge.
