The paper presents a qualitative comparison of 2D and 3D computation of the flow field in a cone shaped turbine nozzle. The calculation yields a surface, S/sub 2/, for a given conical stream surface S/sub 1/. The S/sub 2/ stream surface represents the curvature of blading passages. This formulation is typical for the inverse problem. Based on a surface it is possible to design the shape of the blade. Results of 3D computation by means of FLUENT have been presented and compared with assumptions in the 2D model.
