STUDY OF TAYLOR INSTABILITIES AND TURBULENCE IN LUBRICATING FILMS

1977
The development of the wavy mode of Taylor vortices in the flow between a rotating inner cylinder and a stationary outer cylinder has been investigated by visual observations using a stroboscopic technique and by inner cylinder torque measurements. Radius ratios of 0.874, 0.911, 0.950 and 0.975 have been tested for the concentric and eccentric cylinder

Fluid Dynamic Foundation of Turbulent Lubrication Theory

A S L E Transactions, 1964
A critical examination of Constantinescu's theory of turbulent fluid film lubrication has been undertaken. Several of its anomalies were traced to violations of certain well-established basic phenomena in turbulent shear flows. A new approach, which is free of some of these objections, has been made.

Turbulent Lubrication—Its Genesis and Role in Modern Design

Journal of Lubrication Technology, 1974
Turbulence, a phenomenon well known in fluid flow, was first reported in journal bearings and thrust bearings in 1949. The observations were of higher torques and greater temperature rises than were expected from lower speed data. The transition from laminar behavior occurred at a Reynolds’ number corresponding to the predicted occurrence of Taylor ...

A Theory of Lubrication in Short Journal Bearings With Turbulent Flow

Journal of Fluids Engineering, 1958
Abstract Short journal bearings operating in the turbulent-flow region have been studied. Expressions for the pressure distribution, the load capacity, and the attitude angle have been obtained. Also the condition of laminar flow is shown as the special case of the present study.
