Abstract : The work of Hornung and Perry (1982) is reviewed in which the essential concepts of two-dimensional separation were extended to three-dimensional steady flow, and the vortex skeleton model and electromagnetic analogy were introduced. The model is extended to give a simple topological rule by which the vortex skeleton of a flow can be established from the structure of the wall streamline pattern. The important question of the occurrence of smoothly starting separation without zeros in the wall shear stress, is examined in the light of a new local solution of the Navier-Stokes and continuity equations.
