Numerical Investigation of Impeller Leading-edge Profiling on Vortex Suppression and Performance Enhancement in a Pump-as-turbine

Centrifugal pumps operating as turbines (PAT) offer a cost-effective solution for micro-hydro power plants. However, their hydraulic performance is compromised by flow separation at the impeller’s outer diameter. This study conducted a transient numerical analysis to evaluate the hydrodynamic effects of modifying sharp...
