Abstract

The results of complex design-theoretical and experimental studies of the flow paths of the PL20 model hydro turbines for the modernization of the Kremenchug hydroelectric power station are presented. The experimental studies were performed on the universal energy-cavitational stand of PJSC “Turboatom”. The experimental dependences of the model’s relative efficiency on the reduced flow rate are given, as well as a comparison of the energy and cavitation characteristics of the tested flow paths with improved rotor blades and guide vanes for optimal hydro turbine operation.

 

Keywords: kaplan turbine, flow path, multi-purpose power test facility, model tests, rotor
