If the transition occurs quite far away from the airfoil surface, it may happen that the turbulent flow wedge cannot reach the surface again. Thus there is no reattachment and the bubble stays open. Such a flow field with a thick area of separated flow causes a high drag and usually the lift breaks down. The same happens when the angle of attack is increased beyond the maximum lift. |
