Abstract: A turbomachine has, on its inner casing (5) and on its shaft, recesses into which shrouds of rotor blades and/or of guide vanes (2a) protrude. The recesses are configured with wave-shaped contouring arrangements (10), which extend over their periphery. The contouring (10) extends over axially extending regions of the recess and consists of periodic elevations and depressions (14, 15) in the radial direction. They can also be effected on the radially extending regions of the recess and on the shrouds. The undulation-shaped contouring arrangements are used to counteract existing pressure fields and to reduce performance losses due to mixing processes between the leakage flow and the main flow.

Abstract: An apparatus for redirecting a medium flowing in a pipeline. The apparatus includes a plurality of individual tubes and at least a first perforated plate and a second perforated plate having a plurality of perforations, wherein the first perforated plate is provided in the region of the inlet and wherein the second perforated plate is provided in the region of the outlet for the purpose of holding and guiding the individual tubes. The number of perforations in the two perforated plates corresponds to the number of individual tubes, wherein the individual tubes each bend in a central region by a predetermined bending angle, wherein the bending angle of each individual tube is so selected, that the individual tubes form a bundle having an essentially circular cross section. The individual tubes extend in the bundle essentially parallel to one another, and wherein the inlet region and the outlet region of each individual tube are straight.
