TY  - JOUR
AB - Astudy was conducted ofthe factors that cause anomalous EHDfilm shapes in 1-dodecanol lubricated contacts –i.e.a thickened central plateau and an exaggerated outlet constriction. This has ledto the hypothesisthat, in the region wherepressuresexceed~0.44 GPa, dodecanol experiences slip, which reduces the average lubricant velocityand causesan elevated film thickness in order to maintain flow continuity. The analysis suggests that slip mustbeoccurringat, or closeto, the faster moving surface, since a discontinuityin the flowmidway through thethickness of the film wouldnot affectthe average speedof the lubricant. Based on this hypothesis, an equation has beenderived to predict the anomalous central film thickness as a function of applied slide-roll ratio and this has beenvalidated by comparison with experimentally measured central film thickness values. Further support of this hypothesis is provided by traction test results showing a discontinuity occurring close tothe onset of slip.
