A NOTE ON THE STABILITY OF FLOW IN NON-CONCENTRIC ANNULI

Abstract

At the thin film widths encountered in journal bearing lubrication, it is reasonable to expect that the instability of the flow between two concentric rotating with the inner cylinder rotating will occur in the form of Taylor vorticies. For continuous fluid films in non-concentric annuli Taylor vorticies can also be expected to occur as observed by Coles. In this case a pressure gradient is set up around the cylinders, and this effect was considered by examining the stability characteristics of the local velocity profiles at various cross sections.
