The steady incompressible inviscid flow past a 3D airfoil with a sharp trailing edge TE is not uniquely determined unless the vorticity released into the wake at TE is prescribed. In the physical flow, this must be done in such a way that the flow velocity u is finite at TE (Kutta condition). In this paper, the explicit singular behavior of u at the trailing edge is determined using recent analytical results by Kondrat'ev and Oleinik, and the Kutta condition is enforced by removing the… Expand
