When the surface of body has a discontinuity of tangent across the edge line, infinite velocities are possibly induced at the edge point by the self-induction, which is produced by the distributions of source and doublet on the surface element containing the concerning edge point. Considering physical characteristics of flow such an infinite velocity should be eliminated in some cases, for instance, at the trailing edge. In the present paper some fundamental characters of the theory are first introduced, and eliminating the singular terms of induced velocity at the trailing edge an expression of the Kutta’s edge condition is obtaind, which is useful to determine the circulations around a three-dimensional lifting body. This trailing edge condition containes some continuities of components of vortex vector parallel and perpendicular to the trailing edge, through the body and wake surfaces. It is found that these relations can be used as a matching condition between body and wake, giving the starting value of vortex vector at the wake initiation. Similar relations can also be applied to the separation edges, from which vortex sheet issues.}, pages = {183--208}, title = {On the potential theory of distributed singularities and its edge condition for a lifting flow of three-dimensional body}, volume = {26}, year = {1975} }
