The wall of a turbo machine having a cascade of blades comprises a first platform facing a first channel between the blades in the cascade of blades, and a second platform facing a second channel between adjoining cascade of blades on the upstream side and the downstream side and having a circumferential outline having a distribution of radial position. With such an arrangement, loss due to disturbance of flow through the gap of axially adjoining walls can be reduced.
La paroi d'une turbomachine ayant une grille d'aubes comprend une première plate-forme tournée vers un premier canal entre les aubes dans la grille d'aubes, et une seconde plate-forme tournée vers un second canal entre des aubes adjacentes de la grille d'aubes sur le côté amont et le côté aval et ayant un contour périphérique ayant une distribution de position radiale. Avec un tel agencement, la perte due à une perturbation de l'écoulement à travers l'espace de parois axialement adjacentes peut être réduite.
