Abstract
é descrito o uso de meios porosos externamente pressurizados na vedação de eixo para turbomáquinas, para vedações simples, vedações em série (tandem), vedações duplamente opostas, e vedações sem ventilação. esses arranjos proporcionam benefícios significativos, tais como: (a) a pressurização externa permite que as faces de vedação congeladas se abram antes da rotação; (b) a pressão é distribuída uniformemente através da face de vedação, em vez de permitir que a fuga passe sobre ela; (c) são possíveis baixas taxas de fluxo de gás injetado; (d) as faces de vedação são auto-defensivas devido à pressão uniforme no espaçamento; e (e) é possível a eliminação completa da ventilação do gás de processamento. através da utilização de vedação com meios porosos externamente pressurizados, é possível uma drástica simplificação do projeto da vedação, bem como do projeto do painel de vedação e tratamento de gás.
