Effects of surface texture on journal-bearing characteristics under steady-state operating conditions:
TL;DR: In this article, a numerical approach is used in the analysis of texture effects on bearing characteristics and the results from investigating the performance of bearing surfaces with spherical dimple textures suggest that contact characteristics such as minimumfilm thickness, maximumpressure, axial oil film flow, and friction torque may be improved through an appropriate surface texture geometry and appropriate textures distribution on the contact surface.

Discharge coefficients of orifice-type restrictor for aerostatic bearings
TL;DR: In this article, an experimental study conducted in order to determine the supply hole discharge coefficients of externally pressurized gas bearings was conducted, where air consumption and pressure distributions were measured as a function of supply pressure and air gap height for several different orifice and pocket sizes.
