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.
