Abstract

PURPOSE: To prevent separation of stream line of flowing water and generation of secondary stream and reduce the loss in flowing water by froming the grooves almost along the stream line on a runner vane.
CONSTITUTION: A runner vane 1 is divided into several partial turbines, and the inlet angle, outlet angle, and outlet clearance of each turbine part are obtained. If the number of revolution of the runner is given, the stream line 4 can be determined. A plurality of grooves 6 are formed along the stream line 4, and a projection 7 is formed between grooves 6 and 6. Thus, the water introduced fromthe inlet part is guided by the groove 6 and flows along the stream line, and separation of the water flow from the stream line is prevented, and generation of the secondary stream can be also prevented.
