A study is presented of high-pressure squeeze films between flat disks which approach each other at a constant velocity. The dependence of the viscosity of the oil on the fluid temperature and pressure is included in the momentum and energy equations. A single dimensionless parameter which involves only fluid properties determines whether the load capacity will be greater or less than that predicted by an isoviscous analysis. Excellent agreement is found between the results of a numerical analysis and the results of experiments in which mineral oil is confined between steel boundaries.
This paper presents the results of an analysis of fluid flow in high pressure hydrostatic bearings and seals which can be modeled as infinitely long, closely spaced, rigid parallel plates. The flow is laminar and at low Reynolds number. The fluid is Newtonian with a viscosity which is an exponential function of temperature and pressure. The effect of the temperature variation across the fluid film is found to be extremely significant, and limits the application of the integrated adiabatic energy equation to a narrow range of the parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
