Unformatted text preview: The nonexistence of drag (D'Alembert's paradox), (b) the relation between lift and circulation around the body (KuttaJoukowsky 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). Wingtip 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. 360390, 454468...
