主 题：fluid film friction speed profile flow rate continuity lubricant rheology plug flow
摘 要：To further extend knowledge about fluid film friction in elastohydrodynamic contact,it is important to examine how lubricant *** this paper,several film thickness results obtained by interferometry technique for different kinds of experiments were analyzed and discussed based on lubricant flow *** of two steady-state and two transient experiments are *** speed profiles that can explain observed film thickness distributions were *** is shown that major part of present experiments can be explained by a single speed profile known as a plug *** finding is in contradiction to usual linear speed profile predicted by Reynolds equation.
