lift drag naca
 
1 Attachment(s)
Hello,
I'm trying to simulate naca airfoil but getting not the right cd and cl.
Span of the naca is 0.8m and chord is 0.3m. With an angle of 0 degree I have an Aref of 0.052m^2 (0.8m * 0.065m). I use simpleFoam with LaunderSharmaKE turbulence model and yPlus ~ 1. Now I think about that my values in the controldict to calculate lift and drag are not right.

In blockMesh I have created one cell in z - direction with 0.8m (span).
I don't know what is wrong!
Please help

Thanks in advance
