Possibly Euler or possible-stream calculations predict the stress distribution about the airfoil surfaces approximately properly for angles of attack underneath stall, where they could miss the whole lift by around ten–twenty%. The mixture in the wingtip vortices and the vortex sheets feeding them is known as the vortex wake. : https://electric-garage-storage-l66431.ja-blog.com/33514382/a-secret-weapon-for-garage-ceiling-lift
