The coupled rotor-dynamics issue is always one of the most important and difficult research
for multi-stage pump system due to the complexity of multiple fluid-induced forces and multi …

The influence of sealing components on the rotordynamic stability of turbomachinery has
become a key topic because the oil and gas market is increasingly demanding high …

The stability of rotors in turbomachines is affected by the labyrinth seal where driving forces
are generated. Recent research results have shown that the preswirl has a significant …

To improve the pressure capacity of the magnetic fluid seal with a large sealing gap, a new
type of stepped magnetic fluid seals was firstly proposed based on magnetic fluid seal with …

This paper presents a novel method of labyrinth seals design. This method is based on CFD
calculations and consists in the analysis of the phenomenon of gas kinetic energy carry-over …

The labyrinth seal is widely used in turbo machines to reduce leakage flow. The stability of
the rotor is influenced by the labyrinth seal because of the driving forces generated in the …

The reliable prediction of the effect of various labyrinth parameters on leakage rate has not
been reported enough and a theoretical prediction of the labyrinth performance for different …

An efficient and automatic attenuation technique for the whirling motion of rotating
machinery can be achieved by supporting the journal boxes elastically and providing them …

Nowadays, bulk‐flow models are the most time‐efficient approaches to estimate the rotor
dynamic coefficients of labyrinth seals. Dealing with the one‐control volume bulk‐flow model …

The current paper investigates two particular features of a novel rotary split engine. This
internal combustion engine incorporates a number of positive advantages in comparison to …
