Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2 Based on the analysis of literature sources on the topic of the work, the ways of expanding the pump-turbine operation range in turbine mode to 40-100% of rated power were chosen. At the hydrodynamic stand ECS-30 of the Pidgorny Institute of mechanical engineering problems of the NAS of Ukraine were conducted experimental studies of the model of the pump-turbine flow part of the Dniester PSP with the original runner ORO5217 in turbine and pump modes, energy characteristics were obtained. Numerical studies of viscous incompressible fluid flow in the model of the original version of the pump-turbine flow part of the Dniester PSP in a wide range of turbine modes at the design pressure were performed. A comparison of experimental and numerical studies was carried out. Product Description popup.authors popup.nrat_date 2022-03-09 Close
