PERFORMANCE OF SYMMETRIC SLOT-ENTRY HYBRID JOURNAL BEARING IN TURBULENT REGIME

In slot entry bearings, slots are made by using slotted shim into the bearing. In recent times, the slot entry bearings were developed by Shires and Dee only for application of hydrostatic bearing. Later on, Stout and Rowe, and Rowe et al. designed and analyzed the performance of slot-entry bearings, hole-entry and recessed bearings compensated by various restrictors. Rowe and Chong presented linearized bearing coefficients for oil lubricated slot entry hybrid journal bearings. They determined dynamic characteristics of slot-entry hybrid journal bearings using finite disturbance and perturbation techniques. The theories of turbulent lubrication in bearings were proposed by many authors in recent years. A detailed review about turbulent theories was presented by Taylor and Dowson stating their limitations. Later on, Ives and Rowe reported the influence of super laminar flow regimes on slot entry bearings.
