Hi,
I have cascade of airfoils with inlet speed=20m/s and chord length=15.2. The airfoils are oscillating few degrees and hence there is mesh deformation. The reynolds no. is around 0.2 million. I am running the simulation on cfx. I did some research, read wiki pages and concluded that SST model could be best choice. But i have some doubt regarding choosing Y+ value as SST asks for low value. I dont know if my mesh is fine enough.
I also know about mesh independence study as a way of finding out but i would like some expert suggestion about choosing turbulence model and Y+ importance for my case(explained in first line).
