Abstract (en)
The turbo machine has a rotor which is supported around a rotation axis in a rotating manner and a housing is arranged around the rotor. The housing has a housing inner surface formed opposite to the rotor in a circumferential direction. A turbulence cancelling unit (19) is arranged on the housing interior surface for reducing the turbulence of the secondary flow. The turbulence cancelling unit wall has a turbulence cancelling unit front wall (24) and a turbulence cancelling unit rear wall (25) curved around edges (23).
Abstract (de)
Die Erfindung betrifft eine Strömungsmaschine, umfassend einen Rotor (8) und ein Gehäuse (4,2), wobei ein Spalt (15) zwischen dem Rotor (8) und dem Gehäuse mittels Drallbrechern (19) derart ausgebildet ist, dass ein Drall einer Sekundärströmung vermindert wird, wobei der Drallbrecher (19) materialeinstückig aus einem einzigen Band ausgebildet ist.
