This paper presents a state-of-the-art survey on the development of the foil bearing
technology. Foil bearings represent a proven technology with many promising features …

This paper offers an extensive review of publications dealing with the modeling, the design,
and the experimental investigation of grooved dynamic gas-lubricated bearings. Recent …

A theoretical finite-element model was developed to study the hydrodynamic effect of micro-
pores generated by laser surface texturing (LST) in a circumferential gas seal. The seal is …

Currently, tiny, high-speed rotating machines frequently employ air foil bearings. Air is
employed as the working medium, however, when the rotor speed is high, the rigidity of the …

A model is developed to predict the hydrodynamic performance of a foil journal bearing. The
model accounts for both the compressibility of air and the compliance of the bearing surface …

Gas foil bearings (GFBs) find widespread usage in oil-free turbo expanders, APUs, and
micro gas turbines for distributed power due to their low drag friction and ability to tolerate …

Since the publication of the best-selling first edition, the growing price and environmental
cost of energy have increased the significance of tribology. Handbook of Lubrication and …

A numerical study of the effect of the bearing surface waviness on the performance of
aerostatic journal bearings is presented. The finite difference method (FDM) and an iterative …

Widespread usage of gas foil bearings (FBs) into microturbomachinery to midsize gas
turbine engines requires accurate performance predictions anchored to reliable test data …

The foil–air bearing (FAB) enables the emergence of oil-free turbomachinery. However, its
potential to introduce undesirable nonlinear effects necessitates a reliable means for …
