Numerical and Experimental Investigation of the Ultra-Low Head Bidirectional Shaft Extension Pump Under Near-Zero Head Conditions

Theoretical analysis, numerical simulation, and experimental study are used to investigate the ultra-low head bidirectional shaft extension pump, especially near-zero head conditions. The results show that under forward operation, at low flow and design flow conditions, the closer to the shroud, the...
