Abstract
A blade cascade of a continuous-flow machine is disclosed. The blade cascade has at least one side wall that is constructed in a wave-like manner in the peripheral direction and has at least one elevation and at least one depression. At least a profile-like rib is integrated in or combined with the side wall, which has a blade profile with a pressure side and with an opposite suction side. A continuous-flow machine with such a blade cascade is also disclosed.
Claims11
A blade cascade of a continuous-flow machine, comprising:
- a first blade and a second blade;
- a first side wall and a second side wall;
- and
- a blade channel, wherein the blade channel is defined in a peripheral direction by a pressure side of the first blade and by a suction side of the second blade and is defined in a radial direction by the first side wall and the second side wall;
- wherein at least one of the first side wall and the second side wall includes a side wall contouring, wherein the side wall contouring is wave-like in the peripheral direction and has an elevation, a depression, and a rib that has a blade profile with a pressure side and a suction side.
