Abstract

L’aube refroidie et renfermant une cavité (4) parcourue par un fluide de refroidissement circulant entre deux parois principales (2, 3) est pourvue de pontets (11) joignant les parois (2, 3) afin de promouvoir des turbulences dans l’écoulement. Ces pontets sont munis de reliefs (13) à leur surface extérieure, qui augmentent leur efficacité en accroissant les échanges de chaleur entre le fluide et la matière de l’aube de diverses manières. Figure pour l’abrégé : Figure 2C.The cooled blade and containing a cavity (4) through which a cooling fluid circulates between two main walls (2, 3) is provided with bridges (11) joining the walls (2, 3) in order to promote turbulence in the flow. These bridges are provided with reliefs (13) on their outer surface, which increase their efficiency by increasing the exchanges of heat between the fluid and the material of the blade in various ways. Figure for abstract: Figure 2C.
