The invention relates to a device (10) for influencing the flow in a turbomachine (1), which device comprises a housing (1a) and at least one blade ring (9), which has a plurality of blades (15) and rotates within the housing (1a). There is a gap (11) between the housing (1a) and the blade ring (9), which gap is continuous in the axial direction (x) and has a discontinuous height around the periphery of the blade ring (9). By means of the gap, the gap flow over the blade ring (9) is locally increased and the flow in the boundary layer with respect to the housing (1a) is stabilized. |
