The paper presents the results of design, numerical, and experimental studies of models of pump-turbine flow passages for heads up to 200 m. The task was to improve the performance of the ORO170/5217 pump-turbine, which is successfully operated at 1-4 power units of the Dniester PSP. Using the softw...
