Evolution of Unsteady Internal Flow and Rotordynamic Characteristics of Siphon Vertical Axial-Flow Pump During Start-Up

The start-up process of a siphon vertical axial-flow pump is accompanied by rapid internal-flow reconstruction, transient hydraulic loading and unsteady rotor response, which directly affect the operational stability of the pump system. In this study, the unsteady internal flow evolution and rotordynamic characteristic...

Transient Internal Flow and Energy Conversion Characteristics of a Siphon Vertical Axial-Flow Pump Hydraulic System During Startup

Siphon vertical axial-flow pump systems are widely used in large-scale low-head pumping stations, irrigation and drainage projects, urban flood control, and water diversion engineering, where safe and stable operation is essential for hydraulic system reliability. Compared with steady operating conditions, the startup...
