Assertion: airfoil's lift | /r/Desires | circulation
Facets:
value: in the flow around the airfoil
type: OTHER
Source sentences:
text: The problem arises because lift on an airfoil in inviscid flow requires circulation in the flow around the airfoil (See "Circulation and the Kutta–Joukowski theorem" below), but a single potential function that is continuous throughout the domain around the airfoil cannot represent a flow with nonzero circulation.
