This paper describes a design procedure for the determination of the geometry of the blading of the turbomachine with prescribed thickness and bound vorticity distribution. The boundary conditions are discussed in order to have a properly posed field problem. Optimised 2D cascade design example is shown. The quasi 3D “S2” - “S1” stream function formulation is developed. The design of guide vanes downstream of a lateral inlet casing is described. A new approach by introducing a potential like function to treat the 3D rotational flow is also formulated.
