Abstract
Una turbomáquina axial (1) presenta un arreglo de alabes, que está formado por alabes (3) con un canto delantero (8) y una punta de alabe (15) libre que se extiende radialmente, y una pared anular (13) que rodea al arreglo de alabes con un lado anular interno (14), estando la pared anular (13) directamente adyacente a las puntas del alabe (15) formandó un intersticio radial (16) entre las puntas de alabe (15) y el lado interno anular (14), en donde dentro de la sección axial frontal a la punta del alabe (15) la pared anular (13) en el lado anular interno (14) presenta una depresión radial periférica (17), que en la distancia radial (16) a las puntas de alabe (15) que se van a introducir, de tal forma que a lo largo de la distancia de flujo principal de la turbomáquina axial (1) el curso de las protuberancias radiales del lado adyacente al intersticio radial (16) se adapta al curso de la depresión radial.
