Abstract EN
The present study analyzes pump sump flows with various discharges and gate submergence.
Investigations using a three-dimensional large eddy simulation model and an acoustic Doppler velocimeter are performed.
Flow patterns and velocity profiles in the approaching flow are shown to describe the flow features caused by various discharges and gate submergence.
The variation of a large-scale spanwise vortex behind a sluice gate is examined and discussed.
The suction effect on approaching flow near the pipe column is examined using numerical modeling.
To gain more understanding of the vortices variation, a comparison between time-averaged and instantaneous flow patterns is numerically conducted.
Additionally, swirl angle, a widely used index for evaluating pump efficiency, is experimentally and numerically examined under various flow conditions.
The results indicate that the pump becomes less efficient with increasing discharge and gate submergence.
The fluctuation of the free surface over the pump sump is also discussed.
