Abstract

CONTROL DE LA EROSION A TRAVES DE LA REDUCCION DEL TRANSPORTE DE HUMEDAD POR EL FLUJO SECUNDARIO. UNA TURBINA DE VAPOR (10) QUE INCLUYE UNA PLURALIDAD DE HILERAS DE ALABES GIRATORIOS (18, 20) ENTREMEZCLADOS CON UNA PLURALIDAD DE HILERAS DE ALABES ESTACIONARIOS (14, 16) TIENE UNAS BARRERAS DE AGUA (34) QUE SE EXTIENDEN SUSTANCIALMENTE A TRAVES DE LOS LADOS DE SUCCION (36) DE CADA UNO DE LOS ALABES (22) DE AL MENOS UNA DE LAS HILERAS DE ALABES ESTACIONARIOS (14, 16), ESTANDO POSICIONADA CADA BARRERA DE AGUA RELATIVAMENTE PROXIMA A UN EXTREMO RADIALMENTE EXTERIOR DE UN ALABE RESPECTIVO Y APROXIMADAMENTE PARALELA A UNA PARED EXTREMA ADYACENTE (12) DE LA TURBINA (10), CON LO CUAL SE REDUCE LA EROSION DE LAS ARISTAS DE LOS ALABES GIRATORIOS DEBIDA A LA HUMEDAD TRANSPORTADA POR EL FLUJO SECUNDARIO.
