In this paper, we present a review of the experimental identification of dynamic parameters
of bearings in a rotating machine. Major emphasis is given to vibration-based identification …

A wide-ranging treatment of fundamental rotordynamics in order to serve engineers with the
necessary knowledge to eliminate various vibration problems. New to this edition are three …

In this paper, we present a critical review of the experimental estimation of the rotor dynamic
parameters (RDPs) of different types of seals. The main focus is on rotary seals for high …

Selected test results are presented for an annular gas seal using a smooth rotor and a hole-
pattern-roughness stator for a supply pressure of 70 bar, three pressure ratios, three speeds …

Rotor dynamic and leakage coefficients are presented for a labyrinth seal that was tested at
a supply pressure of 70 bar-a and speeds up to 20,200 rpm. Tests were conducted at …

Nowadays, most studies on the dynamic properties of annular gaps focus only on the force
characteristics due to translational motions, while the tilt and moment coefficients are less …

A novel double-wall-hole honeycomb seal (D-WHHCS) is proposed in this paper. D-
WHHCS is designed based on a traditional honeycomb seal (HCS) by drilling double holes …

Overall cooling effectiveness was determined for a full-coverage effusion cooled surface
which simulated a portion of a double wall cooling gas turbine blade. The overall cooling …

Annular seals are primarily used to control the leakage in turbomachinery, such as pumps.
Consequently, annular seals substantially affect the stability of turbomachinery. Designing …

Electric submersible pumps (ESPs) utilize grooved-rotor/smooth-stator (SS/GR) seals to
reduce leakage and break up contaminants within the pumped fluid. Additionally, due to …
