Flow losses in common vanned pumps such as centrifugal pumps have been widely
studied, while less research attention has been paid to side channel pumps that are …

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 …

A pump-as-turbine is a hydraulic machine that can operate as a pump and turbine at the
same time. Pump-as-turbine happens to be the most appropriate method for meeting the …

In this work, the unsteady Reynolds-averaged Navier–Stokes (URANS) and three hybrid
Reynolds-averaged Navier–Stokes-large eddy simulation (RANS-LES) models are …

Pressure fluctuations in double-suction centrifugal pumps are greatly affected by the flow
rate and rotational speed. An experimental investigation was carried out to determine effects …

The precessing vortex core in the draft tube of Francis turbine is investigated using entropy
production method. The high-fidelity Delayed Detached Eddy Simulation (DDES) method …

The variable-speed energy efficiency prediction model (EEPM) of subsea disc pump is the
key to achieve double gradient in deepwater drilling, and it has also been the difficulty of …

This paper seeks to predict the performance of the side channel pump by considering the
influences of different wrapping angles. Firstly, three pump cases 1, 2 and 3 are modeled …

This research utilizes the Ω vortex identification method to address the turbulent flows in a
single-stage side channel pump, to comprehensively characterize the three types of …
