Abstract

"TURBINA FRANCIS". Uma turbina Francis com um formato aperfeiçoado de lâminas, que pode reduzir as cavitações geradas na superfície das lâminas ou reduzir o fluxo secundário em torno das lâminas, é fornecida. Uma turbina Francis compreende um eixo rotativo, uma coroa, uma pluralidade de lâminas, e uma banda. A coroa pode girar como eixo rotativo. As lâminas são dispostas de forma circunferencial na coroa, cada uma das quais incluindo uma extremidade interna como uma borda traseira. A banda é acoplada de forma coaxial com a coroa pelas lâminas. O eixo rotativo, a coroa, as lâminas, e a banda como um todo giram na direção da turbina durante a operação da turbina. Um perfil projetado da borda traseira em um plano perpendicular, que é perpendicular a um eixo central do eixo rotativo, é curvado na direção oposta à direção de turbina pelo menos no lado de coroa.
