http://web.mit.edu/drela/Public/web/avl/AVL_User_Primer.pdf WebAt higher angle of attack the air was accelerated more, so more energy is lost to friction. At some point the kinetic energy is exhausted and the air comes to a standstill relative to the wing. This point moves upstream with increasing angle of attack. When this happens, static air will collect and build up, causing flow separation.
