Abstract (en)

[origin: WO2016173595A1] The invention relates to an inlet nozzle (1) for a radial, diagonal or axial-flow fan, comprising an inlet section (3) that is circular in cross-section, has a radius of curvature, and tapers in diameter in the direction of flow (4), characterised by the presence of a measure or a flow element on or in the curved surface (5) of said inlet section for the purpose of forcing turbulent boundary layers in the flow, which can counteract a stall in this region. A radial, diagonal or axial-flow fan comprises a corresponding inlet nozzle (1).
