Following the classical theory of wu different kinds of streamsurfaces have been introduced. The complete three-dimensional result is approximated by a combination of blade-to-blade streamsurfaces (s 1 surface) and s 2 surfaces between the side walls of the diffuser. The geometry of each of the stream sheets depends on the others.
