Abstract

ENVOLVENTE DE TURBINA EN LA QUE LE FLUJO DE PASO DE FLUIDO, AL ABORDAR EL RODETE DE LA TURBINA, TIENE LAS CARACTERISTICAS DE UN VORTICE LIBRE IRROTACIONAL CENTRADO EN OTRNO AL EJE DE ROTACION DE LA TURBINA, CON UN BAJO NIVEL DE EXCITACION DE VIBRACIONES AERODINAMICA DE LOS ALABES. CONSISTE EN UNA ENVOLVENTE DE TURBINA QUE RODEA LA PERFERIA DE UN RODETE DE TURBINA QUE TIENE UN EJE GEOMETRICO DE ROTACION; LA ENVOLVENTE INCLUYE POR LO MENOS UN PASAJE DE FLUIDO SUSTANCIALMENTE EN ESPIRAL QUE TIENE UNA ENTRADA EXTERIOR PARA ABARCAR LA PERIFERIA DEL RODETE DE TURBINA. CADA UNO DE LOS PASAJES ESTA DEFINIDO POR UNA PAREJA DE PAREDES LATERALES AXIMETRICOS OPUESTOS, CUYOS DIAMETROS EXTERIORES ESTAN PROXIMOS A LA PERIFERIA DEL RODETE DE LA TURBINA, Y POR UNA PARED EXTERIOR QUE SE EXTIENDE ENTRE LAS PAREDES ALTERALES. TURBOCOMPRESORES DE ESCAPE EN MOTORES DIESEL.
