Abstract
resumo patente de invenção: "turbina hidráulica e instalação de conversão de energia, compreendendo essa turbina". essa turbina hidráulica (1) compreende uma roda (2) que gira em torno de um eixo de rotação (x2), sob a ação de um fluxo de água principal (f1) indo de um conduto forçado (5) em direção a um tubo de aspiração (8), ao longo de um trajeto, de escoamento (5, 6, 7, 2, 8) que passa através da roda (2). essa turbina (1) compreende, além disso, primeiros meios (102), dispostos no exterior do trajeto de escoamento do fluxo d´água principal (f1) e permitindo misturar, por um lado, um fluxo de água secundário (f2) coletado no trajeto de escoamento e a montante da roda (2) e, por outro lado, um gás contendo oxigênio (a2). essa turbina compreende, enfim, segundos meios (110) de injeção, a jusante da roda (2) da turbina, de uma mistura água-gás (f3) realizada nos primeiros meios.
