Abstract

An analytical perturbation stream function procedure is established for po- tential flows about lifting airfoils, which exactly enforces the fundamental Kutta condition. Using Green's identity, this formulation is transformed into an equivalent boundary integral equation. A boundary finite element discretization of this equation then yields a linear system for the efficient determination of the airfoil surface tangential velocity and associated lift 1 Introduction For many years boundary integral equation procedures, or panel methods, have been widely used for determining the potential flow field about com- plex aerodynamics configurations*. In the potential functio
