Multi-stage centrifugal pumps are frequently used in high-lift applications and consume
considerable energy, but suffer from poor performance and large axial force. The rear …

Amid the escalating global demand for raw materials, the gradual exhaustion of terrestrial
mineral resources, and the rise in extraction costs and energy consumption, the …

A novel multi-stage centrifugal pump with floating impellers is gaining traction in energy
systems because it easily links stages in series for varying high head requirements …

As the urgency of the global energy crisis escalates and environmental protection standards
become more stringent, the industrial sector is placing increased emphasis on enhancing …

To implement energy savings in multistage centrifugal pumps, a return channel is utilized to
replace the origin inter-stage flow channel structure, and then a single-objective optimization …

Axial flow pump with high specific speed and large flow rate has been widely used for ship
propulsion, water transfer and pump station, and now it meets the demand to work in a wide …

Separation flows tend to induce a chaotic flow field that eventually leads to energy losses
and reduced efficiency. The present study performed a multiobjective optimization to …

The multi-stage submersible pump is a power conveyor for low-temperature media, which is
conveyed by the rotating of centrifugal impellers. In this study, the impellers of a multi-stage …

In this paper, a novel bat algorithm with an asymmetrical weighed variational method
(AWVM-BA) is proposed. The proposed algorithm employs the BA with a point-to-point …

Centrifugal pumps with multiple stages and floating impellers provide a convenient option
for easy adjustment, boasting advantages such as easy head adjustment and efficient …
