Abstract

L'invention concerne un composant (10) de turbomachine comportant une paroi (14) présentant une face interne (18) et une face externe (16) opposées, la paroi (14) comprenant au moins un orifice de refroidissement (12) pour permettre à un flux de gaz de traverser la paroi (14) en reliant fluidiquement la face interne (18) et la face externe (16), l’orifice de refroidissement (12) comportant un perçage (20) débouchant sur la face interne (18) et une embouchure (26) évasée qui débouche sur la face externe (16), l’embouchure (26) présentant une section progressivement croissante vers la face externe (16), l'embouchure (26) comportant en outre une face de fond (28) qui est inclinée par rapport à la face externe (16), caractérisé en ce que la face de fond (28) de l’embouchure (26) comporte une pluralité de perturbateurs de flux (40) formés en creux et espacés les uns des autres sur la face de fond (28).
