Raw input data |
Runner cavitation characteristic |
Runner blade number, b; Operation parameters, P |
Intensity of the cavitation on b as developed while the turbine is being operated in P |
Intensity of the detailed characteristic summed over all vs |
Wicket-gate cavitation characteristic |
Guide vane number, v; Operation parameters, P |
Intensity of the component of the cavitation which is influenced by v, as developed while the turbine is being operated in P |
Intensity of the detailed characteristic summed over all bs |
Global cavitation characteristic |
Operation parameters, P |
Total cavitation intensity in the turbine while it is being operated in P |
Intensity of the detailed characteristic summed over all bs and all vs |
P stands for a set of relevant operation parameters such as power setting, head and suction head.
