At the present time many papers have been published on numerical and analytical methods of investigating separated flows of an ideal fluid. In papers local solutions have been given near the separation point in a two-dimensional case. The present paper examines three-dimensional flows with a surface having tangential velocity separation. A general method is proposed for solving local problems near a separation line, and three concrete examples have been considered. The solutions which have been obtained are of interest for the numerical calculation of the evolution of a vortex sheet. For the first time the possibility has been indicated of breaching the 32 law during separation of flow from a wedge-shaped edge.
