if I remember well I used SST-SAS model with gamma theta and I remember well that you have to pay attention to the turbulent level at the inflow

the BC are the same that I usually use...so I think they could be good.
Transitional simulation, ok. I had some simulation like your some years ago but on a flat plane.
It's not very simple to...

You are right, about y+ but if your simulation is laminar, y+ as no sense.
about the angle of attack, 12 degrees is probably not so big to change the mesh, but i think it depend by the difference...

Hi,
I think your ideas to change the AoA are the best.
You can't think to remesh everytime you need to change the angle of attack.
Obviously when the AoA increases, the quality of mesh decreases...
