Fundamentals of Gas Lubrication.
Abstract
Fluid film lubrication is an exceptional mechanical process in that viscous shear stress contributes directly to the useful function of developing a load capacity. Although viscosity also causes bearing friction, the equivalent lift-to-drag ratio of a typical hydrodynamic wedge is in the order of 1000 to 1, which compares favorably to a high performance wing. Lubricant compressibility is the distinctive feature of gas bearings in contrast to the more common liquid lubricated bearings. Although basic concepts such as the hydrodynamic wedge are still applicable to gas bearings despite of lubricant compressibility, many additional features in gas bearings are unique and require separate attention.
