Hi every ones,

I am doing simulation for 3D NACA 0012 wing.
I use 3 different tubulent models:
k-e realizable
k-w SST
SA
The boundary conditions are:
Velocity inlet
Pressure outlet
wall

My question is how to set the turbulent parameters for the input and output bcs such: k,e,I,L,...
I also want to calculate the lift and drag coefficient acting on the wing surface. But I am not sure about the reference values such: area, length. I set the reference area=chord*span and the reference length=chord. Is this right or wrong?

Thanks you

I want to compare with experimental data from NASA experiment. So, how can I know these turbulent conditions?
