Comparing to pumps with moving parts water-jet pumps have a lower efficiency and surface
roughness is an important factor for these types of pumps. The aim of this simulation study is …

Adding back vanes to the rear shroud of centrifugal pumps is sometimes practiced in order
to alleviate large axial forces. Effective design and flow characteristics of back vanes remain …

Due to the lack of understanding in the flow mechanism of the hub plate crown, the current
calculation of the disc friction loss and the axial thrust in the centrifugal pump often uses …

A stainless-steel cantilever multistage centrifugal pump was taken to study the transient
response characteristic. The axial locus under different working conditions was tested …

Wall roughness in centrifugal pump side chambers significantly affects flow behavior and
overall pump performance, yet current research in this area is limited. This study investigates …

This paper studies the flow characteristics and disk friction loss of the rear chamber in a
centrifugal pump at a design flow condition with six values of the balance holes at diameters …

The even more stringent limitations set by the European Commission on pollutant emissions
are forcing gas turbine manufacturers towards the redesign of the most important …

The flow inside axial-flow type multi-phase pumps is unstable at the conditions of high-
speed and high gas volume fractions. The transient dynamic characteristics induced by the …

Subsea production fluid is quite often characterized by the presence of frac sand, which
causes wear within the pump, and alters the performance envelop. One of the design …

An excessive rotor axial thrust in any turbomachine can cause critical operational problems,
and rotor axial thrust balancing has always attracted much attention. The present numerical …
