Abstract
sistema, método e sistema de turbina a gás. trata-se de um sistema que inclui uma turbina com uma seção de expansão configurada para a expansão de um fluxo de escape em uma direção a jusante, de forma que a seção de expansão inclui uma pluralidade de estágios e uma seção de difusor acoplada a jusante da seção de expansão. a seção de difusor recebe o fluxo de escape ao longo de um trajeto de escape e um fluxo de energização ao longo de uma parede, e a seção de difusor inclui a parede que compreende uma superfície interna, de forma que a parede é disposta em torno do trajeto de escape, e uma porta de energização disposta na parede em ou a jusante do último estágio da pluralidade de estágios da seção de expansão. a porta de energização é configurada para o direcionamento de fluxo de energização ao longo da superfície interna da parede para a energização de uma camada limite ao longo da parede, e uma primeira pressão do fluxo de energização é maior do que uma segunda pressão do fluxo de escape na porta de energização.
