Abstract

Méthode réduisant l'érosion du carter par le réfrigérant liquide. Elle comprend l'application sur la surface d'un film continu 23, s'étendant sur la circonférence, de liquide de refroidissement afin d'absorber au moins une partie de l'énergie cinétique des gouttelettes, et le maintien de l'épaisseur du film entre des valeurs limites prédéterminées au cours du fonctionnement normal de la turbine à gaz. Application aux turbines à gaz.
