Disk friction loss is remarkably significant in low specific speed centrifugal pumps, originating from the complex flow interference within the rotor-stator cavity. To reveal the hydrodynamic mechanism and energy dissipation characteristics of this loss, this study investigates the flow in the rotor-stator cavity under...

Pressure pulsation of pump-turbines under part-load operation exhibits pronounced multi-scale and strongly coupled characteristics, which are closely related to the hydraulic stability and vibration safety of pumped storage units. In this study, the part-load operation of a pump-turbine under turbine-mode conditions is...

Unsteady cavitation affects the hydraulic performance and reliability of mechanical engineering components such as hydrofoils, pumps, and turbines. Its numerical prediction remains challenging because standard one-fluid RANS simulations may overpredict eddy viscosity in the vapor–liquid transition region and suppress...
