Özet:

 


This study reviews velocity-pressure changes in spiral case, rotor and outlet pipes, force-torque values affecting the turbine rotor, vortexes in the outlet pipe, and pressure changes and vibration effects on two models with different numbers of rotor blades. The study evaluates the effect of different numbers of rotor blades on the flow and the effects on turbine components to obtain maximum turbine power. Furthermore, this study evaluates the relationship between the number of rotor blades and guide rotor blades on velocity-pressure interactions. The analysis determined the turbine rotor blade number to be 17 (Model 1) and 20 (Model 2) and the wicket gate angle was altered between 12°-48° to analyze the effects on turbine characteristics (velocity, pressure, torque, vortex, and power).
