Hey there, and thanks for using the forum!
I can see that you are using a wall function model for the wing. If you want to predict flow separation and the stall effect, you need to use full wall resolution, as outlined here:
There are two methods in observing this in a CFD simulation, by modelling the wall or fully resolving the wall.

Be aware that you will need to modify your mesh setup to achieve a y+ < 1. Refer to this pages:
There can never be a last word in regard to the axioms of any physical theory. All we can ask of them is that they lead to conclusions in agreement with observation. Sooner or later more refined observations will find the weak point in any set of physical axioms. Nature is far too complicated to be completely described in a few equations. - J.L. Synge (1938)

Before World War II, Johann Nikuradse (known from the Nikuradse Diagram) took a bunch of velocity meas…
