Unformatted text preview: The nonexistence of drag (D'Alembert's paradox), (b) the relation between lift and circulation around the body (Kutta-Joukowsky theorem), and (c) the indeterminacy of the circulation in 2D potential flow theory. 10.7 The Kutta condition: an ad hoc criterion, derived from experimental observation, that allows potential flow analysis to be used to establish the circulation (i.e. lift) for a 2D shape with a sharp trailing edge . 10.8 Comments on the fact that viscosity, no matter how "small" it may be in a high Reynolds number flow, is responsible—by causing separation!—for the existence of both lift and drag. 10.9 Qualitative picture of the 3D flow field over a finite lifting surface (wing). Wing-tip vortices, downwash, etc. Induced drag. 10.10 Overview of lift and drag forces on lifting surfaces. Read : Fay, Chapter 11, Kundu Chapter 6 or, for example, Potter & Foss, pp. 360-390, 454-468...
