Flow in thin regions bounded by structured and porous surfaces : applications to load bearings
… on the load capacity and friction force of hydrodynamic bearings has received considerable interest from scientists and engineers. Surfaces of most engineered materials are textured at some level either deliberately to achieve some desired effect or produced by wear and friction of surfaces. …

A Study of Methods for Improving the Dynamic Stability of High-Speed Turbochargers
… engine turbochargers incorporate floating-ring bearings that use the engine's oil for lubrication. The high-speed turbocharger is known to have subsynchronous vibrations at high amplitudes for a wide speed range that could reach 150,000 rpm. The bearing fluid-film whirl instability is the main …

Oil-whirl instability in an automotive turbocharger
… rigid rotors supported on short journal bearings with full-film using rigid and damped supports. In this thesis, the damper supported journal bearing is used to simulate the floating ring bearings that are commonly used in automotive turbochargers. The outer film of the floating ring …

Static, dynamic and levitation characteristics of squeeze film air journal bearing: Designing, modelling, simulation and fluid solid interaction
Bearings today need to be able to run at very high speed, providing high positional accuracy for the structure that it supports, and requiring very little or no maintenance. For this to happen, bearings must have tight tolerances and very low or zero friction during operation. This pushes many …
