Abstract

The invention relates to wall of a turbo machine having a cascade of blades. The wall includes: a first platform facing a first passage between blades in the cascade of blades; and a second platform facing a second passage between adjacent cascade of blades on an upstream side and cascade of blades on a downstream side, and having a circumferential outline having a distribution of radial positions. According to the invention, loss due to disturbance of flow through the gap of axially adjacent walls can be reduced.
