Five-Degrees-of-Freedom (5-DOF) characterization of the stability of a gas lubricated conical bearing of the spiral groove design is determined for bearing numbers up to 500. Perturbation analysis is performed separately for axial, cylindrical and co

The pressurization-flow characteristic of a helical viscous compressor is basic to the design of precision air bearings and non-contact gas seals which make use of the spiral-grooved surface feature. The method of Compressible Narrow Groove Analysis

Compressible Narrow Groove Analysis, as derived in a companion paper (Pan, 1998), is a model implementation of Thin Film High-Resolution Modeling for gas films. This paper describes the numerical procedure to compute the pressure field in a centered

The technique of High-Resolution Modeling of Thin Films is combined with a two-scale analysis to formulate the Compressible Narrow Groove Analysis. The data bank of Fukui and Kaneko (1990) is emulated in the form of an empirical formula to treat the

The rolling stream trail (RST) model introduces a new formulation of cavitation analysis of an eccentric journal bearing; it is presented as a preferred foundation for cavitation analysis of a journal bearing to replace Floberg’s streamer hypothesi

The narrow groove analysis (NGA ) as pioneered by Whipple [1] is a two-scale formulation with an infinitesimal micro-scale. Its shortcomings include: ambiguity in minimum required number of grooves, implied assumption of local incompressibility, viol

A noninertial theoretical model for the dynamics of film rupture has been formulated. Under the transient condition, movement of the rupture boundary is governed by the condition of flow continuity between the film flux and adhered film transport in

The squeeze-film damper, undergoing a whirl orbit as may be caused by rotor unbalance, resists eccentricity of the whirl orbit with a static stiffness which is proportional to the dynamic force carried by the squeeze-film. In addition, the fluid film
