Abstract
This paper presents analytical expressions for the dynamic pressure and dynamic fluid force in axially grooved long journal bearings with consideration of oil inlet pressure and inlet position. The effects of oil inlet pressure (in the range of 0 ≤ over(p, -)i ≤ 1, where the dimensionless oil inlet pressure over(p, -)i = C2 / (μ ω R2) pi) and oil inlet position (in the range of 0≤Θi≤90°) on the static oil film configuration, pressure distribution, and steady state journal position in axially grooved journal bearings are discussed. In this paper, Reynolds-Floberg-Jakobsson boundary conditions are assumed to account for the appropriate starting position of the cavitation, the reformation of oil film at the end of caviation, and the effect of oil inlet pressure and inlet position. © 2007 Elsevier Ltd.
