Abstract

dispositivo de abafamento, motor de turbina a gás e método. o assunto revelado no presente documento refere-se geralmente a sistemas de abafamento e, mais especificamente, a dispositivos de abafamento que podem fornecer quedas de pressão, aprimoramentos acústicos e propriedades de fluxo desejáveis. trata-se de sistemas de abafamento de fluxo de purga altos. dispositivos de abafamento exemplificativos de acordo com pelo menos alguns aspectos da presente revelação podem incluir uma primeira placa de orifício (116) e uma segunda placa de orifício (120) que define pelo menos parcialmente um duto de ar (112) disposto para receber o fluxo (108) de um fluido compressível. a primeira placa de orifício (116) e a segunda placa de orifício (120) podem ser dispostas para produzir o fluxo de interferência cruzada de modo que o fluxo através dos orifícios (114) da primeira placa de orifício (116) dentro do duto de ar (112) seja direcionado na parede da segunda placa de orifício (120) e de modo que o fluxo através dos orifícios da segunda placa de orifício (120) seja direcionado na parede da primeira placa de orifício (116). algumas realizações exemplificativas podem incluir um limitador de fluxo de entrada disposto a montante das primeira e segunda placas de orifício (116, 120).
