Аннотация: Anumerical procedure is presented for analysis of pressure pulsations in hydraulic turbines. Results of its use for description of unsteady turbulent flow in the continuous run of a hydraulic turbine are presented. The numerical method is adapted for results of modeling of turbulent unsteady flow in the continuous rune of a high-head HPP. The structure of the flow beyond the impeller and its effect on the intensity of unsteady processes are examined. Results of the analysis are compared with full-scale data. Good agreement is obtained between the computed and experimental results. © 2015 Springer Science+Business Media New York.
