With the increasing adoption of renewable energy sources globally, hydropower contributes
significantly to energy generation through various schemes ranging from big to small-scale …

The global energy shortage is gradually intensifying. A pump is a versatile device with
significant power consumption in energy conversion equipment. Of the world's total energy …

Cavitation and vibration are crucial characteristics in pumps, which directly contribute to the
safe and stable operation of pumps. Cavitation and vibration are both complicated …

In the present work, the tip leakage vortex (TLV) in a mixed flow pump as turbine at pump
mode is decomposed and reconstructed by Dynamic Mode Decomposition (DMD) for the …

Tip leakage cavitation remains an unsolved problem that threatens the safe operation of
hydraulic machines and plagues researchers worldwide. The objective of this work is to …

Large-eddy simulation is performed to study the turbulence statistics and flow structures of
the water past a rotating axial-flow pump under different flow-rate working conditions. A …

In order to further enrich the theory of rotational stall, this paper explored the mechanism of
internal energy loss in the mixed-flow pump under stall condition based on the shear stress …

To study the effects of the performance of different types of impeller on the vortex pump,
orthogonal test design, which is carried out by combining experimental test and numerical …

In order to explore mechanism and propagation characteristics of rotating stall, the unsteady
flow characteristics of a mixed-flow pump are calculated based on SST turbulence model …

Tip clearance in pump induces tip leakage vortex (TLV), which interacts with the main flow
and leads to instability of flow pattern and decrease in pump performance. In this work, a …
