Comparative Numerical Studies for the Flow Energy Dissipation Features in a Vertical Two‐Stage Centrifugal Pump in Pump and Turbine Conditions

Energy Science &Engineering, EarlyView.
Based on entropy theory, this study presents a comparative numerical analysis of the flow energy dissipation (FED) in a VTSP under two distinct operating conditions: pump condition and turbine condition, both characterized by relatively high hydraulic efficiencies of 88.9% and 87.4%, respectively. In pump condition, the highest FED production occurs in
