The paper proposes a phenomenological interpretation of the effects induced by 3D design techniques on the flow field throughout a turbine nozzle; the analysis is supported by both experimental and numerical tools. In order to point out only the effects related to the application of “leaning” and “compound leaning” techniques, a wide experimental campaign has been performed on three linear cascades. Thanks to the observation of the pressure contour shape on the secondary planes, a physical interpretation of the flow evolution is proposed.

Abstract
The paper proposes a phenomenological interpretation of the effects induced by 3D design techniques on the flow field throughout a turbine nozzle; the analysis is supported by both experimental and numerical tools. In order to point out only the effects related to the application of “leaning” and “compound leaning” techniques, a wide experimental campaign has been performed on three linear cascades. Thanks to the observation of the pressure contour shape on the secondary planes, a physical interpretation of the flow evolution is proposed.File in questo prodotto:
