A premix liquid fuel nozzle has longitudinal air entrance slots (24) into a cylindrical chamber (20). A centerbody (42) produces an axially increasing flow area toward the chamber outlet (32). Liquid fuel is atomized in a specified location (58) adjacent the conical centerbody (42). This area has a high axial shear velocity producing thorough vaporization and uniform mixing before combustion.
Buse d'injection de carburant liquide à prémélange qui comporte des fentes (24) d'entrée d'air longitudinales dans une chambre cylindrique (20). Un corps central (42) produit une zone de flux à augmentation axiale vers la sortie (32) de la chambre. Du carburant liquide est atomisé dans un endroit spécifié (58) adjacent au corps central conique (42). Cette zone présente une vitesse de cisaillement axiale élevée produisant une vaporisation intégrale et un mélange uniforme avant la combustion.
