Моделирование рабочего процесса в проточной части радиально-осевой насос-турбины

Abstract

Presents the results of numerical simulation of viscous fluid in the flow part of the radial-axial pump-turbine Dniester PSP on the head 150 m. The calculations were performed using the software package FlowER-U. Shows the structure of the flow, the analysis of the features of the physical processes and identifies the energy loss in the elements of the flow part in the turbine and pump modes. The results are compared with those of experimental studies on hydrodynamic bench
