    摘要: A fluid turbine comprises a turbine shroud, an ejector shroud, and a means for extracting energy from a fluid stream. The means for extracting energy is located in the annulus between the turbine shroud and the ejector shroud. High-energy fluid can flow through the turbine shroud to bypass the means for extracting energy. Energy is extracted from the fluid passing through the means to form a low-energy fluid stream. The high-energy fluid and the low-energy fluid can then be mixed. The turbine shroud and/or the ejector shroud has mixing lobes to increase the mixing of the two fluid streams.

    摘要: A shrouded wind turbine comprises a shroud disposed about an impeller. The impeller surrounds a nacelle body which is shaped to enhance smooth flow of wind through the impeller. Some embodiments include an inlet and an outlet in the nacelle body, allowing airflow through an interior cavity. Other nacelle bodies may be tapered, flared, include mixing lobes around a trailing edge, or may have other shapes that enhance fluid flow. Some nacelle bodies include an annular groove that promotes flow attachment. Maintaining airflow attachment to the nacelle body within the turbine increases the energy generation capacity of the wind turbine.

    摘要: Shrouded fluid turbines of various configurations are disclosed. The shrouded fluid turbines include an impeller, a turbine shroud surrounding the impeller, and an ejector shroud around the turbine shroud. The ejector shroud may 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.
