| 摘要 |
The use of turbines or turbine-generator assemblies to generate electric pow er has so far required that the tubes disposed downstream thereof, for example suction tubes, are completely submersed in the downstream water. In order to allow for the operation with low or no water level downstream of the turbine using a subsequent tube, the invention discloses a turbine or a turbine- generator assembly, especially a module of such turbine-generator assemblies , which is provided with a means which can at least partially prevent a flow separation from the tube so that the turbine can be operated with an excelle nt efficiency even when the tube is not completely submersed in the downstream water but leads partially or even completely to the exterior.
