Abstract

"TURBINA FRANCIS". A presente invenção refere-se a uma turbina Francis com um formato de lâminas aperfeiçoado, que pode reduzir um componente de velocidade circunferencial gerado no fluxo a jusante das lâminas em uma condição de uma operação de carga parcial, ou reduzir o fluxo secundário em torno das lâminas. Uma turbina Francis compreende uma coroa, uma pluralidade de lâminas, e uma banda. A coroa pode girar em torno de um eixo geométrico rotativo. As lâminas são dispostas circunferencialmente 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. Uma distância Rc pode ser definida como uma distância entre o eixo geométrico de rotação e uma extremidade pelo lado da coroa da borda traseira. Uma distância Rb pode ser definida como uma distância entre o eixo geométrico de rotação e uma extremidade pelo lado de banda da borda traseira. A distância Rc e a distância Rb satisfazem 0,2 <243> R~ c~/R~ b~ <243> 0,4.
