Hi Rob, 

thanks a lot for your reply!

I have read various papers from the literature that study problems similar to my case, and most of them use the SA model. I know some of the limits of this model, such as the inaccurate prediction of separation or decaying turbulence, but these phenomena do not play a major role in my work. and the boundary layer as well. I am interested in what happens in the middle of the domain.
 
as for y+, i know that it is not the main factor in mesh quality. I have also checked other factors such as: Element Quality
Aspect Ratio
Jacobian Ratio
Skewness
and all results are almost unacceptable values.
so my question was how you can improve the inflation layers near the bent or sloping parts.
