FLUID TURBINE WITH MOVEABLE FLUID CONTROL MEMBER

摘要

A shrouded fluid turbine includes an impeller for generating power from a fluid stream and a shroud surrounding the impeller. The impeller and/or the shroud have a moveable member for controlling power generation in the fluid turbine. The shroud has a plurality of mixing lobes on a trailing edge thereof, the trailing edge having a circular crenellated shape. The power generation is controlled by reducing loads and/or controlling impeller speed. Various moveable components are described for the stator vanes and the rotor blades.
