Abstract

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.
