WebJan 10, 2024 · The angle of attack at which flow separation occurs thus depends critically on the Reynolds number. A sharply tapered wing has a high Reynolds number at the root, so smooth flow is maintained to a relatively high AoA. But it has a low Reynolds number at the tip, so the air viscosity leads to flow separation and stall.
