Abstract
An open flume installation for a hydraulic turbine is disclosed having an open flume defined by a floor, a pair of side walls and a back wall of a foundation structure. A water passageway is formed through the foundation with an outlet submerged within the tailwater and with an inlet formed through the floor of the flume adjacent the back wall. The inlet is provided with its axis inclined at a 45.degree. angle. A turbine runner is provided within the inlet for rotation about the axis. A generator is supported above the flume on a support structure spanning the side walls. An inclined shaft connects the runner and generator. The shaft and runner are supported for rotation by a conical vaned intake having its narrow portion surrounding the inlet and having its face portion extending between the side walls. A plurality of stay vanes project radially inwardly from the inner surface of the conical intake to a bearing housing which supports the shaft. The water passageway on the downstream side of the runner is a draft tube having a conical section on a downstream side of the runner connected to an elbow section which has a downstream end having a horizontal axis. A vortex suppressor is provided disposed within an upstream portion of the flume. The vortex suppressor comprises a plurality of plate members spaced parallel to one another and to the side walls of the flume. The plate members extend into a level of water within the flume and encourage laminar flow of water through the flume to the turbine intake.
