Abstract

METHODE DE REFROIDISSEMENT D'UNE AUBE DE TURBINE A GAZ SUIVANT LAQUELLE UNE PARTIE D'AIR SOUS HAUTE PRESSION EST EXTRAITE AU VOISINAGE DE L'ETAGE FINAL D'UN COMPRESSEUR ET EST INTRODUITE DANS UNE CHAMBRE DE PULVERISATION D'EAU, ET L'EAU A TEMPERATURE NORMALE EST INJECTEE DANS L'AIR SOUS HAUTE PRESSION A PARTIR D'UN GICLEUR INSTALLE DANS LA CHAMBRE DE PULVERISATION D'EAU, POUR PREPARER UN REFRIGERANT REFROIDI. LE REFRIGERANT CONTIENT PARFOIS DES GOUTTES D'EAU. LE REFRIGERANT REFROIDI EST INTRODUIT DANS DES PASSAGES PREVUS A L'INTERIEUR D'UNE AUBE DE MANIERE A S'ETENDRE DE LA PARTIE FONDAMENTALE DE L'AUBE JUSQU'A SON EXTREMITE QUAND LE REFRIGERANT PASSE AU TRAVERS DE CES PASSAGES, L'AUBE EST REFROIDIE PAR LE REFRIGERANT, ET APRES CE REFROIDISSEMENT, LE REFRIGERANT EST EMIS DANS UN PASSAGE DE GAZ PRINCIPAL. AU CAS OU LES GOUTTES D'EAU SONT CONTENUES DANS LE REFRIGERANT, ELLES SE VAPORISENT PENDANT LE REFROIDISSEMENT DE L'AUBE, POUR REFROIDIR L'AIR DU REFRIGERANT, POUR SUPPRIMER L'ELEVATION DE TEMPERATURE DU REFRIGERANT ET POUR AUGMENTER L'EFFET DE REFROIDISSEMENT.
