Abstract

trata-se de um dispositivo (11) para controle do fluxo em uma turbomáquina, preferencialmente, um compressor centrífugo; o dispositivo (11) compreende uma pluralidade de lâminas fixas (110) é uma pluralidade de lâminas ajustáveis (111) adjacente à pluralidade de lâminas fixas (110) de modo que cada uma das lâminas ajustáveis (111) tenha uma interação aerodinâmica com uma das lâminas fixas (110); cada uma das lâminas ajustáveis (111) é girada para rotacionar ao redor de um eixo geométrico fixo (100) substancialmente localizado no centro da pressão da lâmina ajustável; o centro de pressão é avaliado quando a lâmina está em uma orientação de referência.
