Abstract

DIFUSOR CON ASPIRACION PARIETAL, SIMETRICO DE REVOLUCION ALREDEDOR DE UN EJE (AA''), Y CON ENTRADA SENSIBLEMENTE AXIAL, DE UTILIZACION EN TURBINAS Y SOPLANTES. COMPRENDE UNA PARED EXTERIOR (2, 3) QUE RODEA EL FLUIDO QUE FLUYE EN EL INTERIOR DEL DIFUSOR DESDE LA ENTRADA HACIA LA SALIDA. LA PARED (2, 3) TIENE UNA RANURA CIRCULAR (1) QUE EVACUA UNA FRACCION DEL CAUDAL ENTRANTE Y QUE TIENE UN TRAZADO TAL QUE EL GRADIENTE DE PRESION MEDIDO EN SU SUPERFICIE EN EL SENTIDO DEL FLUJO SEA NEGATIVO AGUAS ARRIBA DE LA RANURA. LA FORMA DE LA PARED (3) PROVOCA UN SENTIDO DE FLUJO DESDE LA ENTRADA HACIA LA SALIDA Y UN GRADIENTE DE PRESION SUPERFICIAL POSITIVO EN EL SENTIDO DEL FLUJO.
