TLDR
In this article, the governing continuity, momentum and energy equations for a Newtonian fluid, which are coupled, via temperature dependent density and viscosity are solved simultaneously using the finite difference method, to yield various bearing characteristics.Abstract:
Parallel sliding load support has been a subject og numerous theoretical and experimental investigations. Postulated mathematical models suffer from restricting assumptions. The present analysis evaluates thre several models that have appeared and provides an orderly analysis which elaborates on the mechanism that may be responsible for the fluid generated lifting force. The governing continuity, momentum and energy equations for a Newtonian fluid, which are coupled, via temperature dependent density and viscosity are solved simultaneously using the finite difference method, to yield various bearing characteristicsread more

A Laser Surface Textured Parallel Thrust Bearing
TL;DR: In this article, the potential use of a new technology of laser surface texturing (LST) in parallel thrust bearings is theoretically investigated, where the surface texture has the form of micro-dimples with pre-selected diameter, depth, and area density.

Experimental Investigation of Laser Surface Textured Parallel Thrust Bearings
TL;DR: In this article, the performance of unidirectional and bi-directional partial-LST bearing with a baseline, untextured bearing is compared with that of a baseline bearing in terms of increased clearance and reduced friction.
