Bottom outlets are significant structures of dams, which are responsible for controlling the
flow rate, operation, or removal of reservoir sedimentation. The service gate controls the …

Free surface vortex (FSV) is a negative phenomenon in pump stations and hydropower
stations. The purpose of this paper is to investigate the pressure pulsation induced by FSV …

In recent years, tapping the sea for potable water has gained prominence as a potential
source of water. Since seawater intake systems are often used in the infrastructure industry …

The influence of the floor-attached vortex on the pressure pulsation at the pump sump was
investigated using the experimental analysis, and the theoretical analysis according to the …

FAV in pump sump has been a matter of focus for years for the major effects on the efficiency
of the pump, wasting a lot of energy. In order to explore the mechanism of the dynamic …

Research on the S-shaped region of pump turbines requires a detailed understanding of the
vortex distribution law and energy losses under various working conditions. In this study …

The closed sump is a vital inlet structure for low-head tidal pumping stations in coastal
regions. The flow instability caused by roof-attached vortices (RAVs) and floor-attached …

Tangential intake structures with vertical dropshafts are commonly employed in stormwater
and urban drainage systems. Vortex and plunging flows are the two typical flow patterns …

The formation mechanism and the dynamic characteristics of the floor-attached vortex (FAV)
in the pump sump are analyzed, with the velocity gradient as the key factor. The FAV is …

The maintenance of the performance of sump pumps is important to mitigate flood damage
in urban areas and lowlands. However, the air-entraining vortex in the sump leads to …
