Experience curves for modern low-head hydroelectric turbines. Research technical completion report Item Info

This report contains the research findings of an extensive investigation of characteristics of over 300 low-head hydraulic turbines that have been manufactured all over the world. These results are presented in the form of experience curves and regression equations relating the traditional turbines constants of specific speed, speed ratio, unit power, and cavitation coefficient to such parameters as rated head, rated discharge, rated power output, runner speed, and runner diameter. Additional information on the characteristic dimension of the water passages is also presented. Traditional methods of estimating turbine diameter and turbine speed have been checked with actual practice and new simplified methods for estimating turbine diameter and turbine speed have been proposed and verified. A comparison has been made as to how well the draft tube exit velocities on manufactured units are complying with recommended limits. Rather limited success was obtained in characterizing the turbine setting parameter and its relation to the specific speed. Excellent comparisons were possible with published regression relations and experience curves of conventional reaction turbines.
