Abstract
(EN)
Shrouded fluid turbines of various configurations are disclosed. The shrouded fluid turbines may an impeller, a turbine shroud surrounding the impeller, and an ejector shroud around the turbine shroud. The ejector shroud may substantially or completely surround the turbine shroud. The turbine shroud may have a plurality of mixing lobes that form a crenellated trailing edge. Alternatively, the turbine shroud may have a plurality of open slots. Means for directing fluid flow into the plurality of open slots may include an ejector shroud that seals with the turbine shroud downstream of the open slots. A plurality of fluid ducts may also connect individually to each open slot. An external stator may be connected to an exterior surface of the ejector shroud.

La présente invention a trait à des turbines à fluide renforcées qui sont dotées de diverses configurations. Les turbines à fluide renforcées peuvent comprendre une roue, une enveloppe de turbine qui entoure la roue et une enveloppe d'éjecteur qui est disposée autour de l'enveloppe de turbine. L'enveloppe d'éjecteur peut entourer sensiblement ou entièrement l'enveloppe de turbine. L'enveloppe de turbine peut être dotée d'une pluralité de lobes de mélange qui forment un bord de fuite crénelé. En variante, l'enveloppe de turbine peut être dotée d'une pluralité de fentes d'ouverture. Un moyen permettant de diriger l'écoulement de fluide dans la pluralité de fentes d'ouverture peut inclure une enveloppe d'éjecteur qui est scellée à l'enveloppe de turbine en aval des fentes d'ouverture. Une pluralité de conduites de fluide peut également être connectée individuellement à chaque fente d'ouverture. Un stator extérieur peut être connecté à une surface extérieure de l'enveloppe d'éjecteur.
